Cure potency can be capped in 4 pieces of gear. No need for an effect that adds to that. Since you have the ability to have 20mp/tick regen fast cast isn't all that necessary since you can spam heals and never run out. I /sch to spam aoe protects and shells (for other parties in an alliance), stoneskins, and you have your celerity. Whm is a perfect healing mage atm. Especially since you can divine caress in each -na macro. Cures give stoneskin. Ambition gives fast cast and 5mp/tick. What was it you were saying was missing again?
