Root split the Raider from the Man O'War.....wasted the Man O'War x2 and then took Raider by itself and easily burned with 153 AA's (Crit Aff V), Winged Death+Swarming Death+Immolation of Ro, Merc dropped down to 20 and full healed with Chlorotrope then layed another round of my 3 DoT's and ended up with only ~75% mana left to burn whatever.
Either the mob has been nerfed that easy or i am AA/Geared correctly for my level. In either case, not as bad as others posted.
