Starter healer... WHM?

[Roeshel]

Is it? AST doesn't need to stun mobs with Holy. It has a gazillion brokenly overpowered oGCD heals that have hilariously short cooldowns. They're available every single pull, even if you somehow need to dip into using all of them. And it has infinite free single-weaving space even on Gravity, so its damage doesn't get slowed down at all. Holy is the best damage reduction cooldown to be sure, but once its diminishing returns wear off you need to keep an eye on the tank and either clip the hell out of your damage to keep them up with your few oGCDs, or halt your GCD damage entirely to heal. AST is, just like in Stormblood, just a superior WHM in all but a few niche scenarios.

Putting regen and asylum is all you need for your tank to be sustained in a big pull. Even if the mobs are not dead by the time asylum and regen runs out you just reapply regen, use tetra and benison and continue with the spam, only 140 potency lost. You have 400 bonus dmg potency from assize so you still win against ast. WHM has stronger damage output than ast at the current level 80 dungeon content. And I just checked for ala mhigo from stromblood. White mages just deal more damage because they have good sustain.
