Trying this WW Barb shit out and I'm dying like crazy, don't know if I'm not properly geared or don't know how to use the build correctly... LAME.
My Stats
All Res gets to 900 each when war cry is activated.

I think you really should scratch that idea until you get some better gear. I'm making a mule that will be carrying possible gear for when I finally feel ready to go WW, and if I was using what you're using I'd probably wait longer until some better stuff dropped.
Couple of simple things I could suggest but I'm certainly no expert:
You need a much stronger main hand weapon. The skills that are based on weapon damage, the sprint tornado one in particular, are dependent on main hand damage. I don't want to start my WW barb until I have at least a 900 DPS weapon with a socket and crit damage, but you could get away with less. Just not sure what you have will get you very far in act 2 or 3.
Get better gems. Each point of strength is 1% more damage, at the least you should get the next step up from the flawless square. That'd get you 24 % more weapon damage based on your weapon (I think, I'm not entirely sure the formula).
I'm starting to think that if you can't get more life on hit then you should really try to get a belt that has life steal on it.
Your offhand has some nice life on hit, but the other stats aren't doing much for ya. If you could find something with better stat rolls even if the LOH is a bit lower and has a socket, I think you'd have a lot more success.
You should get more resistance too. But I'd think with what you have right now a big issue is not being able to kill enemies fast enough.
Take everything I say with a gallon of salt since I'm not playing a WW barb yet and only going by some stuff I've read. Good luck man
