Not sure how usefull that is when its effectively only increasing curing by 30% and half the trouble is enmity.
It's interesting, though I still don't get the desire for unique gimmicks to justify curing power.
I actually wouldn't mind if sch or rdm went the opposite route to curing large numbers and gained some pretty powerful dmg mitigation abilities. Things like reflect, or elemental absorptions, or even stoneskin2.
