It often seems the most loud ppl are the worst, like this one DK in ToT2 a while ago kept ranting and "correcting" ppl and even straight out insulting them. So I figured I'll check the meters and he was doing something like 20k dps. Noted the raid about it, but for some reason nobody wanted to kick him, which made me wonder whatta hell is wrong with ppl just taking it up the ass like that and not retaliate.
More recent happened just yesterday at SoO lfr. There was this druid whining about wipe and saying things like "what'd u expect, it's lfr" and then soon after was asking strats...so he felt he was above others but didn't even bother to check the damn journal to have a slight idea of the fight. Again the "loudest is the worst" case.
