Anyway, for a more precise critique...
This kind of runs the risk of "gauge bloat", as it were, but most Jobs at this point have two, though most don't charge like this. It seems most similar to SCH, in a way. In fact...very similar, if Aetherflow was generated by casting Broil, Bio, and Art of War. Which...is actually not a terrible idea other than AF spenders other than Energy Drain being potentially OP if they were up that frequently. Anyway, nothing really terrible here as both seem to be useful and do things that give them purpose to exist.
Breaking this down into straightforward terms:
Medica - Generates Aetherflow equivalent.
30 sec CD Sacred Soil that does an Expedient but costs no resource to use and has a 30 sec CD. KINDA OP, like as not... (Note Sprint and Expedient don't say how much they increase movement speed by, so this could be less/equal/greater). Also grants Aetherflow.
Broil IV
Art of War - 50% chance to grant an Aetherflow, has a massive potency increase if used as a combo action after Boil IV and guaranteed Aetherflow generation.
Holy - Except it costs 3x the MP, has a Dismantle effect on all targets, and also does an AOE Sleep. Can be spammed, making this OP as all hells.
Single target Goring Blade that allows the use of Fight or Flight instead of just being one button that does both even though the second button cannot be used unless the first is pressed before it.
Fight or Flight - Except you have to press Goring Blade FIRST.
???? - Zodiark Ex's multi-hit laser thing or non-SMN Ahk Morn that hits multiple times. like those do. 2 min CD damage spell.
Miasma 2 - but it costs an Aetherflow to use and only does full damage on the first enemy making the other DoTs weak and meaning even though it's AOE, you have to spam it while rotating your target. Generates 10 Faerie Gauge, too. Debuffs the enemy for...
Painflare, but requires Miasma 2 to be used first and each time you want to use it again. Costs 3 Aetherflow.
Phlegma - But it costs 3 Aetherflow, has half the CD so it's up twice as often, and shares a CD with...
Plegma Also - but costs 1200 MP as well as the 3 Aetherflow and does a Medica.
Miasma 2, without the DoT (so Art of War) - does all the same stuff otherwise and still costs an Aetherflow, including allowing one use of Painflare, but also also has a 60 sec CD. So maybe more like Plegma than Art of War.
oGCD costs 1 Aetherflow and makes next healing action proc Painflare.
Art of War - except it does more damage, costs 50 Faerie Gauge, generates 1 Aetherflow, and does a Medica.
???? again - but this time it costs 50 Faerie Gauge and only has a 1 min CD.
.
So we have Medica (that generates Aetherflow) and two attack spells that proc a Medica/Assize AOE heal on use, being Plegma with a 20 sec CD that shares a CD with another Plegma that doesn't do the AOE heal and doesn't costs 1200 MP, as well as a Faerie Gauge spender that generates Aethrflow but is otherwise identical (just does slightly less damage).
That's the entire healing toolkit this class has.
It also has a better Expedient; Expedient if it had Sacred Soil's 30 sec CD and generated an Aetherflow rather than consuming one.
It then has 12 attacks, many of which make the Cure 2/Tetra/Afflatus Solace mistake of being 2-3 ways of doing the exact same thing, just costing different resources.
And finally it has 2 attack boosting oGCDs, one of which is Fight or Flight and the other of which is actually something unique, spending an Aetherflow to make a Painflare proc happen on the next heal. So an offensive Freecure generating Recitation, basically. Which I don't mean to make light of, as that's actually an interesting idea.
.
I'd have to play around with it to see what generating the Aetherflow and Faerie Gauge equivalents did and felt like, but this strikes me far more like a Support/Ranged Phys type Job. Something that primarily does DPS and has a few healing procs/abilities on the side. RDM if it had Medica and some abilities that proced or generated it, or DNC with Curing Waltz come to mind. It has about as much healing as RDM would if Vercure were Vermedica instead, and similar levels of utility kinda like Magicked Barrier.
I'm not sure that I dislike this idea as a FFXIV Job, but it very much looks like a Support minded DPS Job, not a Healer Job. It has no single target heals, no mitigation for tankbusters (single target defensive abilities), no quick or efficient spot healing, somewhat odd AOE healing, and it has only 300/400 potency AOE heals. I assume it has a generic Raise, but if not, definitely DNC. If so, then RDM-adjacent support Caster.
As I happen to like RDM (and wish it DID, in fact, have Vermedica - while that would make Healers even more redundant, it would make RDM more cool and fun), I don't dislike this as a Caster or possibly Ranged Physical Job. It's not a Healer Job and couldn't fill the role's requirements in a lot of content, but it could be an interesting DPS Job, honestly.
