Oh man, powergamers drive me crazy too and was a peeve I forgot completely about. It's even worse when RPing in WoW these days, since so many think they're some kind of badass and believe that the accomplishments and stats they have with the actual fighting part of the game carry over. "I KILLED KAEL'THAS SUNSTRIDER, PRINCE OF THE BLOOD ELVES." ...N-No, you didn't. Stop that.

Why do people feel the need to be warlords and high rangers and dragons and uber-powerful dudes. D: What's wrong with just being a rank-and-file grunt, or front line cannon fodder, or a thug, or even just a simple non-combatant type.
