Can your really say that raids in pick up groups always go very well? I often get trolled by people. Sometimes the trolls will just repeatedly try to wipe groups on purpose or will wear inappropriate gear (not even talking about being not geared, talking about wearing a snowman suit when they are the main tank). At least, when I frequent groups with guildmates, they know not to be a total jerk, or odds are, we could take some other person for the next one.

Sure, some pugs go well though, it's always a random thing because there is no accountability. You will never see them again most likely, so people have the sign to act like a total jerk. :P

Not sure I understand anyone's aversion to being in a "static", but I know it's something many don't want and I accept it. Personally I just wonder if it's just this game, or games in general now. When I most recently played Rift for instance, while there were many pug raids, most people always were cheerful about having their static that could get further because they practiced hard and figured it out. There were many alts (I had like 2 or 3 myself) and I would frequently pug raids on my alts and have lots of fun, even occasionally get to the last boss (but not often).
