I always dreamt of being able to kill players of my own faction outside arena and it's now possible.
Never got insulted that much in a video game, peoples are going so mad when they get killed and they don't even have to log another char on the opposite side to do it since they're on my side.
That's one of the funniest thing I ever done in this game, even though I perfectly know they're not reading that, thanks Blizzard, I hope we will have something similar in WoD.
