Its not even about cheap specifically, but yeah it can be used in cheaper evasion builds. Theres literally no other source of evasion within the game that replaces these crystals sadly, so its that they were used in almost all evasion builds outside of people using AP + evasion builds, but those are so few and far between with the state of how cheap accuracy is and how effective stacking DR can be.

Not sure why they opted to leave underwater breathing crystals in for the 5 people in the world who probably do it? I'm also pretty sure if you go into character select it just resets the breath bar anyway so I have no clue whatsoever why anyone would ask for those.

Agility and Precision were removed due to players abusing them.

You want accuracy -> Use accuracy ligthstones, accessories, even magical dim armor (20 accu), elixirs, furniture
You want evasion -> eva lightstones, centaurus belt, sicil necklace, elixir, furniture.

and there are more. 

I personally have bad experience about how "effective dr stacking can be" as a 640dr valk i get melted by players with same gear or even less, due to how cheap and easy human damage is to get, and most players have this human damage cuz there are spots that require these crystals for a better hourly value.

Submerge might be a little useless, but for me as a player that do work on manor furniture and need to dive underwater to look for treasure chests, not goin to say ebernuth nol hunters need those aswell.

by removing Agility and Precision, yes, they nerfed carpet meme shai builds and those players that didn't have money for dawn and ominous rings will be mising out. IMO this is a great change since gauntlets (average gearscore, not gearlord like you see in RBF tanking 10 ppl at once) were quite struggeling in 1v1 and 1vX PvP and evasion was in a rough spot, lets see now how it got fixed 

what do you mean with "abusing them"? In the most standart endgame evasion pvp crystalbuild were like 3 of them, cause there arent any other crystals to use for evasion that arent already in the set at this point. And every evasion counts in the endgame. If they would give us more expensive or rarer evasion crystals that would add HP or whatever to it, I would be more than happy to get those instead. 

Its not like only red players use those crystals to get around breaking gear while getting the evasion. Its basicly the worst evasion crystal there is in the game, but the only one you can use, if you have the better ones in ur set already. 

And that DR sucks is a whole other problem....rather than nerfing evasion UNINTENTIONALY, they should nerf dmg overall or buff dr instead. This has nothing to do with the evasion crystals tho

Source on players abusing agility and precision crystals? You're also missing the point of the post

Ok so breaking it down, 640 DR as a valk isn't even that much compared to the AP people are able to get now with overall gear creep + triple debo set, not to mention a flat increase in 10% special attack damage to nouver etc. What you're mentioning also about the ease of access to human damage etc, is exactly why they shouldn't have removed them in the first place, since its a lot easier for people to run them without trading off accuracy if it isn't needed as much.

If you place some value on sumberge, the +1 mp recovery on hit crystals were added back and so were the ones that give +10% air attack.

Also I'm not sure what you are talking about when you say carpet meme shai? Theres no other way that shai is playable in the game if you want to be remotely successful at playing it. In terms of guantlets etc, yeah perhaps people will have less accuracy in the game since it won't be as necessary but if people don't run accuracy what are they going to use instead? Either AP or DR, more DR means the damage gauntlets do in return is going to be diminished in return.

Also this is all assuming that this removal was intentional when theres no evidence to suggest in the patch notes, or from any official source that it is, given that they already added back crystals that people specifically asked for, its more likely an error on their part.

they removed mobfeeding? haha. How?

Also OP, I agree, but you said instead twice in your thesis sentence.

KR just had protection added to players who are hit by PvP from losing crystals by dying to mobs within a certain time after being attacked.

Fighting in mobs, get hit by PvP, die to mobs within 10 seconds, treated as PvP death and the person that last hit that person gets a karma penalty.  This will take away griefing on Arsha by a lot.

:EDIT

Copy paste from global lab notes below.

• A system has been added to prevent other adventurers who have activated Forced Attack (Alt+C) from incurring death penalties if they are killed by a monster within a certain period of time during battle.
  • If a character is killed by a monster within a certain period of time after receiving a forced attack (Alt+C), the character will not suffer death penalties, including crystal destruction.
    • In the above situation, the character's disposition value will be reduced if he activates forced attack and attacks another adventurer.

Not sure if karma penalties for alt + c will apply on arsha? Regardless thread is getting a bit off topic...

Someone asked a question, I answered it, I don't know how answering a question is off topic.  But w/e you do you.
