Well, that's not how it works. ShO/Grit always reduce damage by 20%, and Defiance always increase healing received by 20%, so, whatever the stats are, you'll always end up with the same result. Keep in mind that if the healer's stats are really high, they're also healing PLD and DRK for a lot of HP.

What is true, however, when you compare damage vs healing, is that it's too easy for healers to refill huge amount HP, so that the whole tank stance is less and less useful...which favors WAR over PLD and DRK.
