I don’t understand how you are having issues, you are clearly doing something wrong, I had a few pieces of heroic gear and cleared both areas for the max soul ashes. Pick better powers next time? I don’t know, I line up powers based on the rng ones i get from the start, by the end I was doing over 60% increased dmg from the powers I got along the way and synced them up right, fight lasted less than 30s
