I did see a few times waaaaay back in like 2.0 where people would kick others right before boss to let their buddy in for a 2 min clear. I was the tank so they didn't dare touch me lol. I voted no, it went through anyway since according to SE, 50% is majority, and then I bailed out. Was I an asshole, probably but I won't stand for that behavior. The person that got kicked as I remember, played pretty intelligently. I haven't seen that happen in all 3.0 or 4.0 though. Maybe I was just lucky. I did report the others though. Let SE deal with it.
