Quote from Nuvianits quite logical that you have to sacrifice something for the speed of this build, in this case it means 1 passive and axes/maces in the favor of animosity and mighty weapons, which I'm fine with.
Some people seem to forget that they reduced the cost of WW and that they buffed animosity, personally i never kite with run like the wind anymore, run like a wind is not exactly an expensive spender, i can keep up WW and run like the wind in all fights, now we get reduced fury cost on WW (which is the biggest fury eater in this build).
Even with 35k HP i almost never have to leave my "whirlwind/tornado circle" to regain back life, WW is our main skill for healing (at least mine), and it got buffed.
Hopefully this post wont come back and bite me in the ass, but I'm quit sure this build will be just as viable (or very close to it) if people switch to mighy weapons and animosity.
I have had some poor luck with drops and have to gear my barb in a slightly different way. The end result being what Nuvian described. It takes me about 1 hour and 50 min for a full act 3 clear with the following stats
7k armor + current enchantress buff value
1000 resist all
54k dps With BR up
24% movement speed
48% crit with BR up
I have my gear setup for more of a defensive point of view in light of high dps > survival items in the AH costing rather absurd amounts of gold. I use the animosity passive currently and its quite nice. I find it very useful when dealing with molten ranged packs i have to chase down. My gear is swapped out for different items at the moment but will change them back around 4pm EST time to reflect my stats listed.
