In end game content, it is becoming regular for paladins and darkknights to, while main tanking, parse as high as warriors or in the case of A11 savage, higher on average. Warriors lose 25% damage from being in defiance while paladins lose 15% from shield oath. Warriors gain 5% from deliverance while paladins gain a massive 75 potency attack after every auto and dark knights gain a virtually permanent 15% increase to all damage. Almost all of warriors impressive points, namely berserk and fell cleave, have become severely lacking in the face of goring blade or scourge.
High damage is a key part of what makes warriors viably applicable in raid and not having it has almost pushed double paladin into the meta.

TL;DR warrior damage is suffering, how can they put warrior back in the spot it traditionally filled as a high damage off tank without making it broken?
