KKL, I'm not really sure what you mean by that.

Xefas pretty much got it right. Barbarians are generally considered to be right in the middle in terms of power, and that'll put them notably lower than ToB classes and infinitely lower than casters.

Since the Barb has nearly the same problem as the Fighter while playing where you just Rage, charge, attack, and repeat the maneuvers really add some variety. Since I didn't alter the normal class features too much, aside from removing Trap Sense, I tried to balance the maneuvers against Rage.

It's not terribly inventive, but then that's why you post it for comments, eh?
