Sometimes when mobs are hit, they go into what I can only think of calling hit-stun. The little animation of them 'getting hurt' if you will, and during they do not attack. I'm wondering how effective it might be to use this to avoid taking damage.
The barbarian and the monk both seem to have a few abilities that hit enemies all around them. My thinking was, that even if you're surrounded by mobs, as long as you're spamming these 360 degree dmg abilities, the monsters will be in a constant state of 'taking damage stun' and won't actually be able to hit you.
Does this happen reliably enough? Or is it just a chance on hit? I've seen quite a few posts about survivability in Inferno; about damage reduction stats, diminishing returns, and healing, but nothing on this.
