Lets Disect what the healers are getting and see where some issues might be

[DotsNnots]

I'd argue the biggest issue is they "balanced" DPS, but then enormously imbalanced healing, and overall made the classes look less engaging.

While this definitely is accurate, I think it misses some other big points that are issues in balance:

WHM
Mobility & Clipping
Giving us instant cast heals isn't really a solution. Unlike an r2 equivalent that you can whenever needed, heals aren't flexible to the point of being able to go out whenever you want them to. We'll have a bit more of an option with the afflatus skills in ShB, but it's really really not a solution.

oGCD Heals
Not really solved, we got like a half solution in the form of a re-branded and still GCD cure2 and medica, which, we didn't really need. They're resource free, and you get a 225p damage potency rebate on them if you get the misery cast off (so these are null towards the end of a fight!), but we didn't really get a full fix here.

Raid Utility
I feel like I've been asking for this for four years. You can never balance healers when two bring rDPS and one doesn't. And you cannot balance one healer's pDPS to compensate for rDPS. It's not like a DPS class where they have consistent rotations. Healing per fight is too variable to have a consistent pDPS measure, and having one healer with high pDPS nurtures toxicity where their co-healer always feels burdened to use their resources first. Meaning, using an aetherflow stack on indom instead of energy drain, because that's more rDPS than a WHM using Cure III. The logic is correct, but compared to healing with an AST where they don't have to use the same resources for the same reasons, they end up feeling bitter.

AST
Mobility & Clipping
Gimped a little bit in that they'll likely use some lightspeeds for double weaving card draws to get a 6% divination, but otherwise still pretty solid since they can slide cast everything, weave everywhere, and not care.

oGCD Heals
Gimped a bit by the CU nerf, but star is still star

Raid Utility
Brought to heel, which I think is better for overall role balance. I'll save the comments on the new mechanisms to get cards and use them for a different post

SCH
Mobility & Clipping
Mobility is still essentially the same as r2 still gives them movement options. But the clipping portion is much much worse. They have r2 to weave, but the issue is how much they'll have to use it with fairy skills all rendered as oGCDs and the new oGCDs they have means to use any of their big buttons they need to weave somehow. So, you'll see a lot more r2 uses to get these oGCDs out and that's going to feel gross.

oGCD Heals
Well these are a little busted aren't they? Hello sacred soil. Who's the crazy one who said scholar couldn't heal by the way? They were already OP before!

Raid Utility
Still there, chain got nerfed a touch but I don't really feel like that bothers scholars as much as it does other classes.

Regarding WHM, something I see a lot of people failing to realize is that we lost Largesse. A lot of people look at Temperance like a buff, saying "Oh, and now we can do this for heavy healing moments!" ...except we already did have a tool that used to do that, from level 45 onward (so it worked in leveling dungeons for keeping tanks up during large pulls) and with a far shorter recast timer. The 10% damage reduction added is nice, but at the cost of a far larger recast timer and getting it waaaay later, it's not a good price.

No it's come up.

Oddly enough WHM's first lost Divine Seal (20% inc healing) and it was given to everyone as Largesse. Then that was taken away and given back to WHM as Temperance.

SE loves to take stuff away and give the very thing they took back later under the guise of "improvement"

Divine seal was originally 30%, on a 60s cooldown.

Largesse was 20%, on a 90s cooldown.

And finally this new version is 20%+10% mitigation, on a 120s cooldown, and gated behind max level (won't be able to use it for all content sync'd down).

WHM is like the pinata of jobs. 'We need some good skills for our new role skill system!' Go whack WHM a bit, some good things might fall out. Square Enix quickly realized (not learned, that would entail very different results) it's difficult to put candy back inside a shredded pinata.

Truly, this is a job for masochists.

Nvm. I'm an idiot. I read it as Bio, Miasma. My bad.

It really seems to me that whoever is in charge of the healers

1) Lacks Vision
2) Lacks Direction
3) Lacks Competence

Vision:

We have yet to be told a cohesive vision for what SE and Yoshi wants healers to do. This can be easily rectified by putting out a statement.

Direction:

It really does seem like whoever is in charge of healers is surrounded by utter chaos.

* We lost Divine Seal, Stoneskin, and Protect from WHM. WHM got Divine Benision (A better version IMHO).
* All healers got Largesse as a Role Action that can be used in lower level content as well as Protect
* SE then takes both away and bakes Largesse's healing increase into Temerence, which is a lvl 80 skill and can't be used under that level.
* SCH gets Miasma 2, has it taken away from them in Stormblood, Given back in Stormblood (yes the same expansion), and taken away AGAIN in Shadowbringers.

Lacks Competence

Yoshi-P says the new abilities are to "Shore up what's needed" in the current healers

* WHM gets more GCD heals that they don't need
* WHM gets no raid utility that they desperately need
* SCH gets more direct heals for some reason despite being really solid healers
* SCH gets it's DPS kit gutted.
* AST card draw mechanic is essentially a coin flip and if you don't have the right role (melee or ranged) that card is sub par.

It's like whoever is developing these healers has very little clue on how any of them actually play or what they need.
