That's pretty much how I built my barbarian. High DR, intimidate + shaken enhancement, cleave and great cleave (and high halfling saves that more than compensate for my intimidate size penalty).
Of course, this is situational, and you still need to be able to do the DPS when needed. But generally speaking that is not a problem for a barbarian![]()
