Finally went through all the notes and images and put them together. There are about 18 skills per tree, and we've got names and detailed descriptions for almost all of them. I'll be posting a full barbarian play report later today, which will also include some more general barbarian skill discussion. I'm just putting the trees up here now, so the real barb fans can get first look.

A few interesting tidbits.
There are no barb skills that boost Attack rating. Zero. There are about 20 that boost damage. So is there no AR in D3? Or it all comes from equipment? Or it's just not implemented yet in a way that requires skills to boost it?
The barb is really designed to be a combat character. He's got a ton of skills that only work when in combat, and you have to be in combat to generate Fury, which you need to use most of his skills. He gets all kinds of bonuses, from landing critical hits, including +strength, +hit points, +life regeneration, and more.
He's got a skill that cuts his damage taken when he's low on health, and a skill that can actually cause spontaneous resurrection. That'll be an interesting wrinkle come HC time.
I'll check this thread before I finish/post the larger barb write up, so if you've got questions or observations or requests, this is a good place to post them.
