Seriously, there's no excuse for this being the hardest boss in the entire game. He's part of the Murkmire DLC, and he makes half of the zone dailies unplayable and unrewarding given the effort. I spent half an hour with a random who had low DPS and of course he was at max HP by the end of it so I gave up. This zone is dead and the gear sucks. Just nerf this boss into the ground.
