How would they even make another healer job though?

That's because they do have it. It's called Adloquium. Effectively 675 potency (25 shy of Cure 2 and Benefic 2) and costs 1000 MP - same as the aforementioned spells. Same with Succor, though the MP values and potency fluctuate slightly between the 3 spells.

Also I've never seen anyone requesting a Physick 2. Probably because Adlo already does that intended function.

I can't, I just can't.

Adloquium isn't the large heal, it's the "special heal" as Kazrah, stated, or the "gimmick heal" as others might call it. It's also the reason why Aspected Benefic's MP cost increases to match Adlo's while under Nocturnal Sect.

Let's put it this way, maybe then it'll makes sense. SCH has no large heal, without a gimmick attached(shield/HoT), that is on the GCD. The same can be said of an AoE heal, without a gimmick attached, that is on the GCD.

EDIT: So while discussing this with a coworker, I was reminded of something. The whole reason Emergency Tactics even exists, is because SCH doesn't have their own versions of Cure II/Benefic II and Medica/Helios. SE even said something similar to this when Heavensward was coming out. Something about them needing more options for pure heals. So now it's not just me who "thinks" this, it's something from SE themselves.

But I can't keep trying to explain this. I'm done. As long as the skill heal who cares.
