It's not terrible at all, but it would be less dps (it's still a lot more dps than most pug builds). That said, there's nothing wrong with playing what you like. if you prefer the hand axe chains, go for it, most people wont notice the dps difference and handaxe has bigger crit which is fun. If you feel like you need the guaranteed cc from roar, it's probably a better split for you as well.
I am just more curious; it's interesting to me. I would not have thought the barb build would be higher.
