I run into jerks all the time. One time in Pharos This one tank kept mocking me for rolling on the gear drops. I told him I needed it for GC seal exchanges(logical reason as he could see most of my gear was allagen or weathered, i was far better geared than him too).

He went on to make racist remarks towards me, calling me a greedy n* and such. (i'm not African American, but it still pissed me off because it was just rude) I mean I could understand if he was an elitist but he KEPT dying. However, by the time he went too far we were at the last boss, so I decided to put up with it. Barely managed to beat the boss. Blacklisted him immediately afterwords.

Over all though Elitism and racism plagues this game, I don't see that often in any other online based game I've played.
