How would they even make another healer job though?

[Kazrah]

A healer in this game, when you think about it, can be broken up into two main elements: a healing specialty, and a secondary feature.

Healing specialties simply refer to whatever "special effect" is tacked onto a portion of non-basic healing skills in a standard healing toolkit. This is pretty simple to spot via what kind of heals a particular healer job is known for, so HoTs for White Mage, shields for Scholar, and alternation (picking either HoTs or shields) for Astrologian. Typically, a healing specialty is the element which a healer job relies on to both perform its role and to stand out among others in this role. Other examples would include Delayed Heal Triggers like Excogitation, Escalation (heals leaving buffs increasing the amount those heals heal for), and even Periodic Absorption or "Shields over time".

Secondary features, on the other hand, are elements that are usually associated with damage dealt on some level or offering a degree of ease on healing to provide more damage as a healer, but are mainly designed with the purpose of keeping a healing job unique and at least somewhat interesting. For White Mage, this would be extra damage via spells and abilities such as Assize and Afflatus Misery (which I still prefer to call "the fart bomb"). With Scholar, its secondary feature is indirect healing in the form of its fairy, which despite seeming more like a healing feature, is intended to offer ease in healing for the job to do more damage with its basic damage toolkit. Then there is Astrologian, who has its card system that allows for (at least in theory) a means of increasing damage of allies to offset for what damage it can't do. Healing via Damage is a really good example of a secondary feature, as it can offer an ease in healing required and promote damage while not being as broken as it would be if it were a healing specialty (since that means it'd have to be more relied on, resulting in massive balance issues). Other forms of indirect healing such as totems are another good example.

From those two things, you'd follow the basic healer kit shared across other healers:

Basic heal
Large heal
AoE heal
Instant heal
Specialty heal
AoE specialty heal
Raising spell
"Increased healing" cooldown

Basic damage spell
Periodic damage spell
AoE damage spell

I could probably fill it out more, but kinda nodding off. Anyway, after all that, add in some any spells or abilities that would "round out" its overall kit and voila, FFXIV healer.

GNB does through its normal combo, though it's nothing major.

WAR and DRK do that as well, but with their combo ender, not the middle section.

While this seems to be a good generalization, it's a bit inaccurate. SCH doesn't have a Large heal, nor does it have an AoE heal, but it does have the faerie to compensate for the lack of those skills. One could argue overlap in certain areas, but seeing as both AST and WHM have individual skills that fall into the specific categories you listed, the skills SCHs lack cannot be ignored. This is what makes SCH the outlier, which isnt bad, but it's why SCH is a bit more difficult to balance compared to the other two.

Just like Jandor said, Adloquium and Succor serve as the large heal and AoE heal respectively, which is understandable to miss because of how often players forget that damage absorption effects do indeed qualify as healing. The main reason why they are harder to balance compared to standard healing abilities is because it can circumvent the usual ceiling for heals that is "overhealing", and this game isn't the only one that has had to deal with such an issue of balance (discipline priests in WoW say hi). To further impact this for Scholar specifically, there are other balance issues such as factoring in the Adloquium critical effect and faerie abilities that can be used while casting other heals.

SCH has a large heal and an AoE heal, they're rather different in that half of the potency is wrapped up in shields, but they still fit in the "big heal" and "aoe heal" categories IMHO.

Cure II is 700 potency, Adloquium is 300 potency plus 375 potency as a shield, for 675 potency total. Both cost 1000MP.

Medica is 300 potency, Succor is 180 potency plus a 225 potency shield, for 405 potency total. Medica is 1000MP and Succor is 1300MP.

I knew there would be confusion unless I explained further, was hoping that wouldn't be the case, but meh. Based on the categories that were given, Adloquium and Succor would fall under the Specialty Heal and AoE Specialty Heal. SCH doesn't have a true equivalent to Crue II, Benefic II, the Large Heals, or Medica and Helios, the AoE heals. That is why I indicated that the faerie is meant to make up for the lack of those skills, and that there is some overlap in these categories, depending on how you wish to view them. Plus why balancing is a bit problematic, since the faerie is MP free, and other things. But regardless, SCH does not have either of those skills, Adloquium is a Regen and Aspected Benefic equivalent and Succor a Medica II and Aspected Helios one.

That's a rather pretentious way to start a reply...

I wont lie that it could be viewed as pretentious, though that was not my intent. I merely mean it that I knew if I didn't explain, there was going to be confusion regarding the skills. At that moment however, I didn't have the time to explain, and was hoping that inference would kick in, which it did not. If anything, it is my fault for not elaborating in my first post.

What I said still stands however. SCH does not have a "large heal" or an "AoE heal" as it was put. I prefer to call them a second tier single target heal and a first tier AoE heal, but that's just me however.

Absorption effects are simply preemptive healing. Just because the green numbers don't fly up for them doesn't mean that the game's systems don't count them as effective healing.

Admittedly though, if you put in Adlo and Succor as the two specialty heals, then Lustrate and Whispering Dawn (faerie AoE HoT) become the large heal and aoe heal respectively. Sure, you might think "oh no, then you won't have an instant heal", but that would be Excogitation. Alternatively, if you kept Adlo and Succor as the large heal and aoe heal, then the healing specialty for Scholar would become shotgun healing via Aetherflow abilities. Scholar is weird like that, and all the more reason why it can be a pain to balance at times.
