Its really weird, got Qarn again... different tank, we get to the two rooms with tablets before the second boss, get the heads on plates to open them then he takes off without clearing them. I call him back saying "hey tank, we need to clear these rooms please come back", he comes back and says "i am not new, you don't have to tell me" then says he's going to vote kick me. I guess it didn't pass, because i was still in the group or he didn't do it. We get to room before second boss, he walks between the mobs to the boss room... i aggro them, more yelling at me. I've never not killed those. We kill them, then he announces "i have to pee!" he leaves us there for 5 mins waiting on his bodily function. We kill that boss finally, and move on...
