Keystone suggestion - All out attack

Effect: +25-50% more armor or gain 25-50% of armor as evasion. Cant use shields or ranged weapons

Position: warrior side of the tree, can even substitue an less used node.

I love playing warrior and i think the class fantasy is perfect. Unfortunately, shields outclass any other option and makes giant blood mandatory. With a node like this it would make dual wield or one two handed weapon equally viable. The numbers of course should be tweaked to make survivabilty similar, if a little weaker than using a shield. What are your opinions on a node like this?
