I use lp% gear in ud3, and with 60% I can handle half a ud3 normal room with my turtle hermit.
Well, I use normal con gear and I handle UD3 hard room easily but that is because I can one crit shot them. Now classes like dark warriors should also be able to handle it pretty easily but because of the broken damage they can't do shit there. Also with that 60% and decent buffs in retail you would be able to handle the whole room easily in UD3 normal.
