Rage?
Well, reading up on it, apparently having ~50% crit+multi mob tanking with swipe will get you more then enough rage because of the crit-->rage conversion
i dunno...i guess its "kind of neat", but i dont see any real life usefullness for this beyond a science experiment...if evasion tanking is the point here, wouldnt you want to throw a rogue or surival hunter into the mix?
