Power Harrier was a good and fun roaming build until Anet, in their infinite wisdom, gutted it; first with Tome CDs increases, then with the RI nerf. I believe it can still achieve a certain level of success however. It has good healing with good boon support, but now you gotta think twice before popping the tomes because of the insane cooldowns. You can carry Sword and Axe mainhands for the fury uptime, and Fury + RI can get you 50%-ish crit chance, which is still pretty workable.
