Lets assume every no-tank party member has 20k hp and no crits (lets leave rng out of this, values slightly bloated to take fairy in consideration).

Aoe buster drops in and deals 18k dmg.
SCH uses deployment and shields everyone for 4k hp. +Adlo +Deployment tactics
That's 14k that still needs to be healed. +Emergency tactics +Succor +Indomitability +1 aether stack
Roughly 9k hp got healed in 2 gcds, lets have the co-healer/fairy/hots handle the rest.

Adlo+deployment precast for 4k mitigated + 9k healed in 2 gcds for 2386 mp + 1 aether stack and 5 skills used. (energy drain has a rough 900 mp return so we can consider 3286 mp was used)

Again the same buster drops in and deals 18k dmg.
WHM uses divine seal + cure III.
8k damage healed. 10k to go. +Divine seal +Cure III
8k damage healed. 2k to go. +Cure III
Hots/cohealer/fairy can handle the rest

16k damage healed with 3 skills, 1 precast, 3358 mp used.

Literally the same thing, mitigation can only be considered superior if we have a party with 20k hp and buster deals 22k damage for example. Also not doing for AST cause id have to do for diurnal and nocturnal. Should be pretty similar to both above anyways.

This is also what kills WHM, SCH shouldn't be able to heal a buster in 2 gcds even though it uses more ogcd skills and then we have the fights that give you 3 more more gcds to top everyone off even making the heal check more lax to non whm healers.
This was actually balanced on 2.x since succor wasn't able to heal everyone off (no ET), indo didn't exist and you couldn't shield everyone off in 2 buttons.
Putting AST in a similar situation, we don't have a cure 3 heal bomb. We also currently don't need one. We can just mitigate it and heal less (compared to a WHM), but accomplishing the same thing as a WHM. This is done by relying on a combination of healing and mitigation rather than pure healing.

So in using your example:
18k raid wide damage to non tanks.
Disable + Collective reduces that to 14.4k damage (3.6k mitigated).
Synastry + Helios x 3 = 12.3k healed.
Collective HoT 2 ticks = 3.6k healed. (sometimes could get a 3rd tick is timed right)
Total healing done = 15.9k

3 skills used, 3180 MP used (note: basing this of my ilvl which is 247).

I think that's right, but do check my math if it doesn't look right.

There's also sustained AoE healing to consider. SCH cannot sustain heal and in certain fights like A11S, it proper cycling of mitigation and healing is needed.
