A noob lvl 65 warrior here….ok….I spent hours on this guy with hammer and rifle. It sucked. but I just beat him and it was actually crazy easy. I switched to a banner to rez all my guys…once rezzed I just use the bow skills and he melted like butter. just took pot shots at him while using combustive shot to aoe dot the area….and used healing surge to get my adrenaline up to do it again….and kept hitting with the bow standard attack and whatever I could fling at him.
btw…my armor was dead at this point…..so this worked with no armor.
It’s nuts but after hours of tryin him…he was down in like 30 seconds.
Don’t know how this would work with other professions but maybe it will give you ideas.
