So i was in stratholme today with a warrior from SOS Brigade. Asked him before 3rd or 4th boss if he could try tank properly because he missed very much aggro from the mobs. He went crazy and then after the boss kill he ninjaed the hat ive been gringing for. I will post screenshot of this, and the conversation between me and his guildmster @ http://imgur.com/a/4ciXc

EDIT: Found the answer on another thread. Sorry :)
