I had better luck running 4 barbs through act 3 than I did with monks (inferno), I even added one monk and ran with 3 barbs and the resists were nice but didn't feel as optimal. The amount of gold you have to spend to get to act 3 with barbs versus the cost for monk is insane sadly . They were fun but 4 WD's is still face roll on the keyboard :P my barbs are parked for now!
