Paladin needs an enmity/potency buff.

I think there is a difference between attack power increase (50% Berserk) and more damage dealt (Maim 20%). It wouldn't be a flat 170% increase. Once you pop berserk and look at the the attack stat it goes up by 50%. Now the question is does strength outweighs damage dealt?

Just like how reduce incoming damage is better than raising physical or magical defense.

You're right. 50% attack power is NOT equivalent to 50% extra damage dealt. It is in fact a bit worse because the damage you deal involves factors beyond your attack power. FoF is competitive with Unchained and Berserk COMBINED. Good WARs pull ahead because of Internal Release in a lot of real world situations.
