A few zones AFK is acceptable, things come up, any more than that /kick
If things come up leave the game, anything more than one zone is leech territory.
Mute them
I've muted peoples back ground noise but if a guy or gal is simply acting like a dick I'll be happy to put the skull on them or I'll leave the game. I don't like playing matches with ass clowns.
3) or aren't playing with the team (when everyone else is calling you to a particular spot do not aggro everything and then come join them)
Can't control all of the people all of the time, sometimes you just need to accept people won't come and adjust yourself to compensate. People with high promotions tend to stand out in the open.
If it is a rare case fine and I'd never put a skull on a person for aggroing I'd just leave the lobby after the game. If you are going to run off and agrro you;d better clean up your mess rather than letting the enemy attack people who are busy with a revenant or horror.
4) if you repeatedly open the door to the next area as I am collecting a chest I hate killing a revenant only to have someone pull me to the next zone just before I get the chest
Clear the rooms before the zone is finished, almost everyone I play with (have played with) does this. If you are the host, everyone should really be respecting your wishes though. A top 10 leaderboarder unfriended me as I zoned us before she could collect 1 pot. People with 2 million gold stored are so tetchy.
It's not the gold that counts, it's are you paying attention to how i am playing the game that is important.
5) doesn't happen often, but stealing a kill when I'm trying to heal when you have a reaver in the group let them deal with the melee peeps and try to focus on the ranged people
Low Health is better on Reaver. (Health Potion, Regen Potion, Rock Tonic for emergencies.)
