By introducing raid content, here's the logical change:
Raid Paladin:
TC + Ardent Defender + Redoubt + Holy Shield
Raid Warrior:
TC + Critical Block + Shield Block
Solo/5-Man Paladin:
Ardent Defender + Redoubt + Holy Shield
Solo/5-Man Warrior:
TC + Critical Block + Shield Block
In the raid, the Paladin's weaker AOE mitigation (while Blocks are fully effective) is accounted for because the Warrior can give the Paladin the full buff. In the 5-man and solo situation, the extra SBV from Critical Block and Shield Block is not effective to the point it imbalances the classes, strictly in mitigation.
