On a i340 SCH Indom heals for avg 10500 for the cost of an aether stack and 30 second cooldown, while in a full party with vit bonus and or food, i340 players have between 38-42k HP. Heal to 100% with a 10500 heal on a person with 40k HP? Not unless the aoe damage was so pitiful that it barely needed to be healed, but then why would you care about how powerful AoE healing is in faceroll content? It's faceroll for a reason and any of the three healers would trivialize the AoE healing needed in that case.
Indom is not affected by Largesse so it cannot be boosted like Cure III, it has a cooldown so it cannot be spammed like Cure III.
Cure III by itself on an i339 WHM heals for avg 12500 so 2k more than Indom. A Largesse boosted Cure III heals for avg 14500 so 4k more than Indom.
A Cure III cast also gives plenary so can be instantly used afterwards with up to 3 stacks for another instant no MP cost boost to heal for even more and lets not forget Cure III already heals for more than Indom in the first place.
Cure III (550 potency) + 1 Plenary (150 potency) actually gives you 700 potency which is 200 potency above Indom.
Cure III (550 potency) + *2 Plenary (300 potency) gives you 850 potency which massively overtakes Indom by 350 potency.
*used for comparison I realize you would need to cast another AoE to get 2 plenary but there are times where you do end up with 2 stacks just doing what you need to do to heal.
On a i340 AST Earthly Star heals for around avg 15500 (did more tests for average) and has a 60 second cooldown, while in a full party with vit bonus and or food, i340 players have between 38-42k HP. Heal to 100% with a 15500 heal on a person with 40k HP? Not unless the aoe damage was so pitiful that it barely needed to be healed, but then why would you care about how powerful AoE healing is in faceroll content?

Earthly Star is not affected by Largesse so it cannot be boosted, it has a cooldown so it cannot be spammed.
Cure III by itself doesn't heal for as much as Earthly Star but it is spammable and also gives plenary for a free boost and no MP cost.
Cure III boosted by Largesse actually only heals for avg 1000 less than Earthly Star even though it is spammable and gives plenary.
Cure III (550 potency) + 1 Plenary (150 potency) actually gives you 700 potency which is only 20 potency off a powered Earthly Star.
Cure III (550 potency) + *2 Plenary (300 potency) gives you 850 potency which massively overtakes Earthly Star's 720 potency.
*used for comparison I realize you would need to cast another AoE to get 2 plenary but there are times where you do end up with 2 stacks just doing what you need to do to heal.
You can't be serious. The only thing I can conclude is you don't play AST or SCH or even have them at 70 because I would think you would have known all of this I just said if you did or maybe even fact checked before you posted.
I mean yeah Cure III has a smaller range but add up the potency for Medica I if people are too spread out and a massive AoE hits like Charybdis.
Assize (300 potency) + Medica I (300 potency) + 1 Plenary (150 potency) = 750 potency AoE. Stronger than Indom by 250 potency and stronger than a powered Earthly Star by 30 potency and all you had to do was weave oGCDs.
Keep in mind the radius of Cure III is as large as Asylum. If you were standing in the middle of the Asylum you could hit every person inside the Asylum with Cure III if you used yourself as the target.
