He must be a game god to overcome absolutely everything that anyone could ever do to stop him. I personally hope someone else gets his attention, he can only hit people in front of him. Literally if you jump and he doesn't follow nothing will happen to you (Unless someone chains it to you). I carry a scout rifle and get some distance and open fire on his head. He will recharge so you stand and fire. Then throw a grenade in front of you and pull out your shotty. He should be soft by then and the grenade will get him. If not you get each other and he wasted a super, you win. Takes timing and there range can be adjusted but works pretty good for me. Most good parties will all get distance for chaining reasons and turn and fire anyway. Much easier and faster.
