The more I think about it, the my main issue with you dwarven build: It is really contratictionary.

On the one side you are build him to heal as much vitality as possible with every attack. But on the other hand you are saying: I want as much armor as possible, so I don't get damaged at all. So the second aim makes the selfheal is pretty pointless, except if you fail to achieve it.

All that selfhealing would work far better with a build focus on high vitality. But sadly that would hardly work, because you can perma cc-t if you don't have armor to protect your vitality.
