I don't think some people understand the claim system in this game is shared. Even at 50 I still see people for atma mobs and not searching for group but not wanting to team up because they know they can claim it faster lol.

If you really want to punish someone watch them pull and let them die. Then grab the monster and kill it with them receiving no raise.

Honestly the community here is not 180 degrees different. The game might be but the community is the same. They just go for it.
