Retribution turns a tanky build into an offensive build.
Suddenly your sword and board is breaking the enemy's arms when they try to punch him.
You recover their health and armor? Well now your heal effectively does damage.
You used the Shields up ability? Well now you essentially did 100+ extra damage.
While... Leadership is kind of... Overpowered if you know how to take advantage of it... or terrible if you don't (I don't like leadership)
Retribution is flat out good.
