Desert Wind feels really off for a Barbarian; breathing fire, running around a field and such just doesn't feel like the kickassery Barbarian is made of, and for. Tiger Claw is definitely correct and Stone Dragon too; Iron Heart has some maneuvers with Barbarian feel (Iron Heart SURGE!), but the whole idea of weapon mastery is pretty much irrelevant to a Barb.

I would consider making Barbs more of a Tiger Claw-focused class; Bloodclaw Master has the Shifting-ability which is just another form of Rage and overall, Tiger Claw seems to capture the Barbarian best.
