because of people's attitudes?

It seems every time I do them, I have a horrific experience. People are only set on speed running things, and it's just needlessly stressful and unpleasant, because the moment something fails, all they do is yell at each other.

Went into my roulette this morning as a healer, and the tank was doing a pretty sloppy job. (It was Brayflox HM), so one of the DPS proceeded to yell at him, then both DPS vote-kicked him (I seem to be the only one who voted no) and we ended up without a tank...

Since then, I've been pretty discouraged from doing Expert Roulette, since most of my experiences are like that...
