I figure with a shield and all resist gear, combined with shadow power and a decent bit of life per second, life steal, and life on hit, you might be able to survive the damage of most enemies pretty well. DH's should get the same dodge bonus from dexterity as monks, right? so 40-50% or more dodge helps out there too.
Are the melee/close ranged based skills good enough for something like that to work, though? Talking about things like strafe (whirlwind-esque?), Shuriken cloud (seems like the equivalent to sweeping wind for monks), and fan of knives?
