Why would you put in a mob that you have to DEACTIVE challenge mode while his is bouncing you around and has an interupt evey 15 seconds. Combine the 2 and 9 out of 10 times you CAN NOT GET HIM OUT OF CHALLENGE MODE !! You should be clicking him to PUT him into this mode. I don't raid i don't have access to RAID gear, i don't want challenge mode in the first day of an EPAC. Fix it! Or someone post the bug to kill this guy because yet again SOE does an epic fail on a simple mob.
