Paladin need to be review.

Convalescence is also 30% boost in healing on a PLD, compared to 20% for DRK or WAR, except simply by virtue of being a WAR in Defiance, the WAR already has a base 20% boost to all healing taken.

This is a very poor comparison to make as it completely ignores that both PLD and DRK in their respective tanking stances take less damage.
