Honestly, reading this thread it can feel as if the situation is clearly and very chaotic out there, with people who do badly or acting rude showing up on every instances of dungeons, raids, etc... Well, I can't claim that I have played this game for thousand of hours or years like some of you surely have done, but I've played for a while right now and occasions where people were performing really badly, acting rudely, etc, were very very very rare. Not often enough for me to get upset about it when it happens--hey, I sometimes do mistakes too. In fact I've seen more occasions people saying <I'm sorry> or <I apologize> when they screw up.
