Need help with white mage

[Risvertasashi]

So I mained sch in ARR and I haven't touched a healer since then. I decided to level my white mage up. Any tips or guides for how to play it?

The playstyle is nearly identical to Heavensward WHM, if you've seen or heard about that at all.

Healing priority: Regen > Cure > Cure II. Regen is most efficient, Cure II is least efficient. If you have Healing over Time (HoT) effects up, such as Regen or Medica II, try to resist the urge to top people up unless there's actually more damage coming.

Use your oGCDs, such as Tetragrammaton and Asylum, to avoid spending MP on normal heals when you can. Take note that Largesse does not affect oGCD heals, but pairs excellently with Regen and Medical II. If you're below a certain MP threshold Lucid Dreaming should generally be used on cooldown (you'll get a feel for this). Benediction ignores all healing debuffs and can be used to avoid interrupting DPSing if you like.

Assize has three purposes: DPS, free healing, MP recovery. If you, for example, use it in place of where you might cast medica... you avoid spending 1680 MP and get 10% MP back on top of that. You can also just use it purely to do damage. You don't usually want to hold this ability in reserve for long.

Presence of Mind pairs excellently with Thin Air, for either AOE heal spam or DPS.
