This is actually funny the fact you just replied to my post completely out of context. Replied to the second half of my post which completely irrelevant, but missing entirely the first one. But it was expected.
Here's a simple and honest question: What's an i-frame?

As a reminder to @Krastonosezs, the following is what you had said to start with:

Then, Ascenn replied to you with:

Their reply to yours seems spot on. As for the first part of your argument which you argue wasn't addressed, it was already debunked in my essay before you even wrote it here; but it was also addressed in this thread multiple times by both them and me. Here is what I have already said many times over to answer the bogus claim like yours saying "[oh just] find a weakness to exploit or an opening and bait are the keys to a win [against a grab]. "

My answer to that: 

I have heard the pseudo-argument saying that this modality of a class with grab skill against a class without a grab skill is somehow fair because the class without a grab has to patiently wait for the right time to strike while all the time trying to trade damage and getting in range of the grab just to try to fish for that CC... Well how convenient it is to make such a remark from such a high horse! Why should the Grab class have that constant Joker card under their sleeve while the other class has to play under the unfair condition that she may get grabbed at any time while trying to do her work without a grab? This is no argument, either both classes have a grab skill, or preferably none have it. Why should one class always be the hunter, the aggressor, and the other has to always be the unfavored underdog, the prey? This is not balance. No one can tell me grab is fair until they have played as their main character a class with no grab skills from the past two years to present day, because then they would understand the underlying lack of balance that the grab skill brings to BDO.

I am pretty sure I have not left any pro-grab argument un-debunked in my essay, I welcome any new arguments to help illustrate my case.

As for your question on what is an iframe, let's skip right to you telling us what the definition is and construct your argument accordingly if you even have one. Let's stop pretending your asking that question implies anything relevant to your side when you don't even bother acompanying it with an actual argument.

P.S.:

I finally found a hack for this terrible forum-editor to allow me to quote multiple post from different pages! So helpful to expose bogus claims. ^.^

Ah, yes. The tried and true method of class desighn. There are certain features that just have to be universal, you know basic stuff like damage, blocking, Picking people up and shoving them into the earth with the power of a thouusand suns. Even if the feature does not fit the character at all. Next everyone will need the same number of grabs on the same cooldown. Everyone must be the same, no one can be special, till all are Zerk!

I have seen this mentality ruin a lot of games, Group Buffs in WoW and FFXIV for instance. No it's bad, it ruins classes, & it's not good desighn.

You should really try playing all these supposed OP classes with grabs that don't have the universal stigma of being unbeatable in a 1v1 against an opponent who is literally invincible 50-75% of the time in PvP (AT THE VERY LEAST) *like a sorc*. I just make characters when there are exp events to better understand how to fight against them with my main characters. It also helps me get some grinding done that I dread doing normally since I prefer PvP over PvE and there is no way to progress gear without doing PvE. I had a pretty huge eye opening experience when I played all these supposed OP classes that I just didn't understand how to fight against when i first encountered them in the wilds on my main. The first thing I learned was that nobody has a free win button in this game. Victory is decided by many things but it can be mostly attributed to a couple of things. 1. Skill to use your own class. 2. Gear with the right build for your class and last but not least 3. Understanding of your opponents strengths AND weaknesses to take the actions nessecary to maximize the odds of the occurence of events that favor you and not them. To me this PvP is about as balanced as it has ever been in the entire 7 year history it has. I mean it has a pretty good balance as far as gear goes in the sense that Eva Counters Full AP/DR builds but DR counters Accuracy builds that get to counter the Eva builds. I do know this though the more classes they make the more blanket statements like your "everyone gets a grab or nobody does" will just straight up ruin any remaining balance the game currently does have. The proof is that classes without grabs all can win just as many AoS rounds (Musa won more than any other class last season with no grab to speak of) or at least are comparable to most other grab classes. They can or have the ability to get just as many kills in nodewar and siege and most of the skilled players of ANY class can get just as many if not more kills then Zerks who are the supposed king of grabs with 2 whole grabs AND the Zerks get the added bonus of constant BSR funneling to pretty much have on demand 100% BSR and a 200% in their back pocket for anytime the enemy groups to tight. I will agree though that SA/FG at the same time is stupid oppressive and should be removed completely. Like when I play as my Musa for example. I don't have perma I-frames and don't have the range of my hash or witch so I am vulnerable while waiting for a hole to occur and while trying to break the opponents FG. Meanwhile they are completely protected. That is not fair obviously and I honestly think Musa could use like a 10-20% FG shred on a skill or 2 that has longer cooldowns but AoS proves I am just bad and that other Musa are winning against all these opponents anyway. Other than that though my hash witch or musa don't ever seem like I just can't win because I dont have a grab even if I fight against a sorc over a grinding rotation and literally can not touch them. All in all I don't want or need a grab but IF they are going to give everyone a grab then they need to fix the lingering I-frames and get rid of ALL i-frames during skills that do damage. You should never be able to deal damage and be immune to damage at the same time in PvP. That should have been obvious I would think. If it's an i-frame it should be for movement and countering grabs that is it and it should have the exact same cooldown as grabs do. Everyone should have a protected movement skill that is a near spammable SA but not as an i-frame. 2 or 3 classes spending even half of their time in PvP completely immune to everything is just not balanced in any way shape or form. Melee classes should be slightly tankier and SLIGHTLY more mobile to close distance against ranged classes before they die but nobody melee or ranged should get to just completely ignore the need to tank due to not even being able to be hit. Now if everyone does lose their i-frames then everyone should lose their grabs too and if everyone gets a grab everyone should also get perma i-frame movement skills like some other classes in this game to balance it out but without both of these pair of things happening at the same time I don't see how this game could gain any sembelance of balance from these potential changes (at least in my mind). 

I took the liberty to format your post so that it is more presentable to the reader.

You mean like Tamer, ninja, kuno, lahn, etc.? Oh so they aren't 50-75% invinsible? neither is sorc, you might not realize but sorc actually has to worry about stamina unlike those other classes in comparison. And guess what the best part is, of those heavy iframe classes, only sorc doesn't have a grab! What a nice point you brought up to showcase the lack of any criteria and reason for only some classes to have a grab and others not.

I am absolutely not letting you even pretend you get this one for free. Explain how a skill such as the grab-skill is not a win-button when it:

• Has a casting time so short it is basically outside the reaction time-frame of humans.
• Counters everything while having no counter.
• Extremely high-reward for extremely low risk taken for using it
• Simplifies pvp to the point where even a new player with a grab-skill can pose a serious threat to even veterans who lack a grab-skill because, by virtue of having the grab-skill, you don't need to know or care what the weaknesses and openings are of your opponent and, since the opponent doesn't have a grab, the grab user can play more oppressively--you just grab them when they cast a long-winded animation no matter if it is SA/FG, and that is within the radius of your grab-skill's range; to add insult to injury, if your grab skill's nearly instantaneous casting time somehow misses the target, nothing adverse happens to you other than having to wait for you grab timer to replenish (no punishment for missing); all of this resulting in the grab-skill being a win-button.

What other skill do you know of that grants the user a near-instant CC that goes through everything and consequently results in a kill? This is the exact same behavior if we were talking about a skill that did a quintillion points of damage to your health. The grab-skill is unequivocally a win-button. And it's time to remove it or at least give it to everyone. Also, there are so many players that started on classes without a grab and moved onto one with a grab. Their experience corroborates what was already self evident, that the grab skill is a win-button.

Your third point is precisely the basis for my contention. Grab overrides your third point. It takes a class without a grab 3x more effort and skill to fight someone with a grab; conversely, it takes a class with a grab a third of their skill to fight against a class without the grab-skill. As mentioned, even a new player can entirely dismiss your third point just because they play a class with a grab. If you really believe your own list then you should be agreeing with me.

I agree only in that high-end gear is more accessible now than ever to everyone and not just those in the top zerg guilds. However, on the topic of pvp itself being the most balanced it has ever been in history, I cannot agree. PVP currently is in it's worse state of balance ever. I am sure it's impossible to feel for the compulsive reroller like yourself. The best state pvp ever was in was just before the developer introduced the Succesion mode of classes, from then on the developer ignored their pledge to not give so many protected CC, and the game started becoming purely that. A lot can be said about how bad the current state of pvp is but that deserves its own topic.

On the topic of grabless classes like musas "winnng" in AOS, it was already pointed out to you by a few others that this is when paired with grab classes. You conveniently fail to mantion AOS is not duel mode, and indeed statistically due to the fact that 2/3 of all classes have the grab-skill, assuming an even distribution in AOS matchup we would have that musa is statistically going to be paired with 2 classes which have a grab. And thus, your argument falls apart. If anything, musa has done well in AOS IN SPITE of not having a grab. The same can be said for your interpretation of the node/siege performance of musas, at large scale of course a grab stops counting as much since there is only one person you can grab at a time and all the while you are unlikely fighting one but many, whom will blow u up while u hold ur grab; but when it comes to small scale, THAT is where grabs shine as the win button that they are.

At least we do agree on something. but as unskillful as SA+block may be, at least it doesn't CC you through everything like a grab; but yet incredibly, the classes that have this mechanic also have a grab somehow! Why Pearl Abyss? It's like they invented a great defense (block+SA) and a great counter (grab) and then gave it all to the same class. lol

Wow I mostly agree here too, remove all protections from any damage skill and CC skill. I am of the exact same idea when u say that u don't want or need a grab. My contention is that if some do get a grab then I should have one too because there is no reason that they have it over me nor the other classes that also lack them. But again, I'd prefer that no one had a grab skill. I mostly agree with this paragraph, contingent with grabs being removed or given to everyone.

To grab someone all you have to do is click E on them while they are in a standing SA or FG.

To iframe a grab you have to be balls deep inside their brain on a spiritual level combined with the pure luck they haven't showered and you can sniff the pheromones of intent to predict the precise moment they decide to click E. The whole time managing stamina and cooldowns so you don't accidentally cast your "iframe" unprotected. And god forbid, they haven't just baited you and you're on cooldown weaving in an SA standing still like the grand prize in a crane game which hasn't been rigged to lose just waiting to get yoinked into a white van by an old man with duel axes.

Yep seems fair.

To be honest, if you're failing to grab a class. It says less about iframe and more about you not knowing where the SA in their rotation is. Class knowledge people, that shit is free.
