What would be the abuse on the Wookie boss ? Making him burn his own adds ? That sounds absolutely intended to me. How many other bosses has some sort of "friendly fire" thing ? Red Reaper would be one, where you had to move and stay behind of thsoe acolytes whateves. I don't recall walker-kephess damaging his pakcs of thrandoshians with the aoe stuff (would have been nice though,lol)
But what are you going to do ? Positioning yourself so adds are safe and sound ? That's what you do for your group fighting with you :P
Last nite some one showed me the Expoit , I won't tell anyone here simply because I don't do it .
