Most noob looking race/class combos

Noobz that are so bad they get your group killed are annoying. But not as annoying as the arrogant fuck who thinks they know how to play everyone elses' class better than anyone else, all the while babbling on while someone in the group dies, because they weren't paying attention to the action, but were more concerned about instructing everyone else on how to play the game "right"

That, or refusing to add someone to the group because they are the "wrong" class, and then the group wipes because they were short-handed
