I've never been kicked from a dungeon, EVER.
The one thing after the first couple pages, i never seen what the OP's dps was, compared to the rest. The kick may have been justified, if everyone is doing 10k, and he is doing 2k that shows a problem.
But if was doing 7k and they were doing 10k, the kick was unjust and you will just have to deal with it.
