I finished Battle of Ilum last night and the final boss I assume was bugged. His force explosion was doing over 17k (no combat log but that's the highest hp we had) We wiped on him about 4 times before we got him down. I watched a few videos and other groups were not getting one shotted by this ability, but loosing around 30-60% of their hp if it got off. Aside from interrupting that one ability, the fight was a simple tank and spank. He had no other real ability so you could just stack there and run back if you took the knockback. Makes healing easy, heal tank, aoe, heal tank, aoe....
