I've made a few videos showing how you can gear your barbarian for very little gold, how to use it and how to set up your skills to maximize your damage while spending as little as possible.

Since people still seem to be having trouble getting this build to work, I'm going to type out a few key points of how these mechanics work.
1. Battle Rage is your most important ability. If you don't keep it up, you will run out of rage and this will lead to issues.
2. Sprint tornadoes are your main source of rage, not frenzy or whirlwind. If you don't have tornadoes down, you're going to run out of rage.
3. You are not expected to keep Wrath of the Berserker up for 40 minutes straight while farming. Use it on bosses and elite packs with CC abilities, such as frozen or jailer.

added note: Nobody should expect to spend next to nothing and start farming act 4 elites. This build is a great way to get started, and will easily clear its way through act1/2 with very basic gear. You can use that as a stepping stone to gear up a little more for further acts. Even so, I found that I spent far less on this build than an equally progressed tank barbarian would, and continued progressing much faster.

got any videos with your barb in act 3 and 4 because i doubt you can farm elites there with this build.

I can farm act 3 elites, but it's just not worth it right now. With improved gear, farming act 3/4 with this setup is actually a joke, but I'm purposely using mediocre gear to show that you don't need to be decked out to be a progressing damage barb.

What passives do you use?

Wow, that as amazing. You just changed my entire thinking of babas. Holy fuck dude

this build is really clever and really fun to play, however it absolutely folds to anything that can lay down significant aoe ground damage. I've been playing it all day, and the Achilles's heels are myriad. Anything that is shielding, anything that is nightmarish, or any mob that has a natural tendency to spread out and run (i.e. wretched mothers, fallen shaman, skeleton mages)

Use Wrath to negate nightmarish, use Wrath + frenzy and spam sprint and battle rage to keep it up to take down elites that kite you.

blown away. will definetely pass on the tip, props to you, really good build

Your guide was posted on Reddit almost two days ago, and I've been using it ever since to farm Act 1. It works wonders!

I really appreciate it, I keep a more updated guide here: http://www.diablofans.com/topic/56904-how-to-the-tornado-whirlwind-barbarian-video-guide/ so if you're interested feel free to check it out. Hopefully I can post some more video guides on this builds or others soon, and if anyone has specific questions feel free to ask.
