Hah, at least it was for something, the tank could not cope with your DPS.
I was kicked once just by telling someone who was cursing because he could not get into the dungeon, just to be calm, that maybe he was on one quest he had to leave for being able to join, and he got mad at me just for that, and because there were another 2 players of his guild they kicked me, just like that, with the so bad luck that after the deserter on my char was gone, i queue again, and surprise surprise the same nice company, so i got kicked again and another deserter.
Yeah definitely stuff happens.
