So i was on my tank doing some randoms, and i get this rogue, and im like alright cool.  A little into the raid an axe drops, and he puts it in is offhand, and its a slow weapon.  So im like dude, put it in you're main hand.  He yells at me for not knowing how to play a rogue...when he originally had crippling poison in his MH saying that "it helps the tank pick up things" and wound poison in his offhand....and to top it off he had 30k health...so the group just booted him.
