well first, lose the lacunis and get a 40-50 ar bracers with crit-chance. thats houd increase your dps a little bit. second, 600 res buffed with below 900 or 1k loh wondt do any good.you should have crit chance on your helm and bracers. as well as rings (of course) you can get a 600 loh sword with crit damage for a cheap price. next your main-hands dps is pretty low. if you're aiming fora WW barb, low main hand dps isnt a good idea. 40k hp is good enough.
your gloves needs crit damage, lose the res on it and put it on your bracers.. thatll be cheape
