The best part about this "human nature" though is that the same people who will yet at you for a single mistake because of ignorance are the same people who will not explain how a fight works and then will later complain about how terrible the queue times are and how more people need to play tanks. Do they not understand that most of the time it's behavior like theirs that makes people not want to tank PUGs?

I've found that it's easier for me if I maintain the idea that I'm doing them a favor by choosing to go the tank route. If they have a problem with me having to learn something or can't stick around after a single wipe, that's their problem, not mime. I'm not the one with another hour long queue waiting for me if I leave.
