SCH Tips/Tricks/Life Hacks?

[duvvvv]

I feel more comfortable with AST as healer, but I use SCH when I'm confident at healing for the day (whichever DR I plan to get into).
- if you're familiar with the instance, and knows when a big AoE will hit the party, pre-cast succor for less spot heals/indomitability as the latter eats up your aether (time it wisely!)
- don't forget to put fairy on obey, especially when switching from SMN (I personally have my ifrit on sic all the time)
- pray you don't have to use lustrate often, but don't forget to use it for emergencies or after you've rezzed someone (while it's OK to spend your aether)
- if paired with AST, be wary of their stance, let them know to change it if they're on Nocturnal unless you're not planning to use your shields then carry on

About this, pre-casting Succor is generally bad in terms of efficiency. Here is why:
- Succor's full potency (assuming no overheal) is 375. Indom is 500.
- Pre-casting Succor will likely result in overheal, which will consequentially reduce the effective potency you're going to take advantage of (if you only take advantage of the shield, it's only 225 potency).
- On the other hand, Indom is generally used after damage has occured, meaning less chance of overheal.
- Succor is the most expensive SCH spell outside of Ressurection.
- Succor eats a GCD.

Personally, the only situations where I use Succor are the following:
- People will die to the next AOE without a shield (generally this will only happen in Ex Content/Savage, people need to be really low to die to dungeon/NM content AOE damage)
- Having a shield will make healing after the next mechanic much easier (again, generally not applicable to content outside of Savage)
- I'm not wasting effective GCDs - i.e., the boss/enemy isn't targettable at that point, like before they cast their Ultimate skill on Ex primals.

TL;DR: It's more effective to heal AOE splash damage with Indom after the hit since it only costs an Aetherflow stack, than trying to shield it and waste a GCD/MP if people won't die to said hit.

I agree with these numbers, but to clarify, I never said use succor instead of indomitability, and I did specify big AoE not every AoE. also, succor and whispering dawn are the only available AoE heals for an SCH below 52, I think pre-casting succor to mitigate incoming aoe dmg during battle isn't exactly illogical unless, like you listed you're aiming for optimal healing performance.
