I've seen rude jerks playing all 3 roles, but it seems like when I'm a tank, people seem to assume I'm automatically a snob if I don't tank the way they think I should. Overall I'm open to performing the role however the party wants, but it seems like you're damned no matter what. Either you're aggravating someone because you stop after each battle to make sure everyone's ready to move on, or because you move on immediately after each battle, or stop to talk about how to handle something coming up, and it seems like no matter how you approach it, the rude ones get ticked and try to portray you as being presumptuous no matter how you go at it and for every mistake you make.

In these cases, I just leave. Else, when I'm not being targeted, it's usually someone freaking out over 'noobs', to which I usually respond by calling them 'Princess'.
