My idea about BoSanc

This way, we will close in on Warriors, so we only have a 1% damage gap between us.
If Warriors can have an extra 3 damage reduction, boss mobs must be balanced to compensate for that, meaning the non Warrior tanks will have to deal with the damage discrepancy.

Improved Righteous Fury
While Righteous Fury is active, all damage taken is reduced by 9%.

Sanctuary
6% of base mana
Eachtime the Paladin is hit by a damaging attack (even it it´s dodged, parried or blocked) the raid gains Sanctuary, when the target blocks, parries, or dodges a melee attack the target will gain 1 rage, 2 runic power, or 2% of maximum mana.
