I have to play mostly solo, even those 65-75 GRs, bcs in group the ww dmg is just not enuf.
As about leaderboards, also happy ww is there, but maaan, what a squishy build it is.
I can easily go 80+ but impossible w/o pain enhancer, CoE and density combined w good affixes elites.
The rest is paragon stuff as always
Replace the COE with BOM if you don't have the necessity secondary freeze/stun roll for APD. Also, kite a bit when dealing with bad affixes. 40% of the damage came from Dust Devils that spawn trailing your character. It's perfectly legit to lead bad elite to death.
