You can grief pvp players easily in this game.

You can just make tag char without crystals + be guildless. Now you can grind at that spot 24/7. In trash spots like centaurs you 1-shot mobs without any crystals.

If he feeds you to mobs, its useless because no crystals to lose. Without guild he cant gvg you. 

Im endgame player and there is very rarely dfs. I can svitch between 3 guild channels with no cooldown. Also they added more elvia servers. Its pretty empty tbh. But im sure places like centaurs are full.

I learned from the previous posts (which is helpful and informative) that griefing is bad and it can lead to you getting deck or the entire guild deck.

To be honest, your post does not relate to anything. It's bad, in my opinion. Please read the other posts on page 1. I learned a lot from that page. Thanks to them, I can explain it properly to try and be equal to PVP players and respect their space. The same goes for Life Skill / PVE.

i didnt know life skill player grind mobs

from my point of veiw (a pvp player)

pve players and life skillers are usually the ones that want shit garbage changes to my class .

other than that i dont really care what other people do

I dont thik PvP players hates PvE players in general, simply because in this game all players always need to do PvE and LifeSkill activities, because there is not other way to get stuffs in the game.

What I think is that since the game allows and even encourages PvP, players do PK for a variety of reasons, to take the grind spot, boredom, because someone in your guild once did the same thing to them, because they are streamers and they want to look good with their audience, or because they want to impress the girlfriend/boyfriend next to them, because they spilled the coffee... etc., etc.

Fortunately, some of these problems have been alleviated since Marni's private areas were implemented.

The main thing is how you react to this type of events. For example, even if a player belongs to a guild of someone who has done something to me, I will not do anything against that player that do not deserve, because that is the same as looking for someone to pay me, not the one who owe me, and this is cowardice.

Another example is that when I started playing, obviously I didn't have the capability to defend my spot, and if some other player took the spot from me, I would just switch servers and avoid losing time. Today that I am able to defend myself, I simply defend my spot, and every time I have been having fewer problems on that topic.

Simply, don't let others to define your playing time, you define it yourself.
