We would have died if we wore that scummy zerker gear.
Nice kill all the same but as you get more familiar with the fight you can dodge most of his attacks. Not to mention, running 0/0/30/30/10 AH in full zerker plus the 2/2/2 water and monk runes is pretty hard to kill as long as you have your party around you. I run that on my guardian in dungeon speed clear groups since I love having 23 seconds of stability during a boss spike. The only time that guardian dies is if the rest of the party has wiped.
