This is why 4 man content is a problem. In high end 4 man content taking anything not PLD or WAR you are pretty much grieving because of the amount of self healing those two tanks have is light years ahead of the other two tanks.

This is why 8+ man content is huge for healers because that is where their value shines the most. Bloodwhetting was a mistake because it forced devs to give PLD more healing which made them give GNB and DRK a little bit of more healing.
