Bronjahm is either piss easy, or nigh impossible. This hinges, once again, one whether your dps is retarded (stand and pewpewpew ololol) or not(get the debuff, run away then dps the shard down). It's hardest on casters. That ability where he does damage based on how much mana you have is nasty on mages, and makes it a bit of a luck element. Smart healers will focus on people with mana bars, and smart dps will try and empty theirs in p1 asap.
