Diablo III: Reaper of Souls

I've tried out Torment, and my Barb was getting wrecked. Can't WoTB faceroll anymore either, so I'm trying to find an adjusted WW build to still allow me to generate near infinite fury and getting some good life sustain (I heard WW Wind Shear is one way of doing that). I'm saddened that I used to be able to handle MP3-MP4 no problem, now I feel super weak and regain life too slow.

I do love the fact potions are picked up the same way gold is, and heal 60% now. Smart loot is doing wonders for my lowbies.
