Hm, let's give it a read.
I like how you took my WHM Lily concept to use it with Addersgall (abilities can be used with or without it, but it generates something extra if they are used with it up, consuming it in the process)
Personally, I think Kardia should have no recast time. Let people hot-swap it to reward play. It works this way in PvP and I think it's an improvement since it reinforces (and actually FORCES) that SGE is meant to heal via Kardia primarily.
"Healing Actions GCD" = "Healing Spells GCD"?
Why does Diagnosis have no MP cost? I like it's effects otherwise, but it should have an MP cost, imo. Unless we're just going to make all the Healer basic heals work like the old PvP system where they can be cast infinitely with no resource issues? I do like that it increases when used on a shielded target. The Esuna effect seems meaningless, but also harmless, so...
Eukrasian Diagnosis looks good. Streamline Addersting generation.
Prognosis - Again, why 0MP? Also, why the faster cast time than the current one 2 sec?
I DON'T, on the other hand, like what you did with Durochole and Ixochole. The barrier interaction is fine, but making them medium-ish CD instead of resource based I do not approve of.
You didn't change the Hams, which kinda sucks. I like them, but I wish they were useable more often (even if in lesser form), but meh, as it's no change I can't really be upset about it vs the status quo.
Soma - Is that how Papa Lev's worked? I thought it reduced damage taken, not healed damage after taken. I do like the idea of his big barrier thing being a level 100 capstone, but not sure if this form of it or not. I do like the wall protecting people behind it, though, but I feel it should be a damage reduction. It can ALSO refund damage, though. Because why NOT have yet another oGCD that does that...?
Why remove the MP cost of Dosis and Eu Dosis? And why change the DoT name, since that's just slightly more confusing for no reason.
Dyskrasia was renamed (so the Eukrasia version doesn't make anti-sense in Greek), fair enough. It's now ranged because? I guess I don't mind, since I like the option to be at range anyway. Just seems to make it a better Gravity, but whatever. Why does it have an MP cost while Dosis does not? And why bother with the MP restoration then? Why not make it JUST not cost MP to begin with and restore MP? I get you want it to maybe not be used on single target as a go-to spell (but the lower damage should ensure that), so it seems to not make sense. Not to mention it can't be used as a general MP tool and in practice, all AOE pulls (dungeons) will have more than 4 targets anyway, so a flat MP increase with no costs would make more sense for basically all cases.
Eukrasian versoin - Ah, so that's why you changed the DoT name. Why not just give it its own name and say they can't stack? But meh, neutral towards that and I've felt they should have a Eukrasia Dyskrasia that is an AOE DoT anyway. Again, same thing with the MP cost/regen being a bad idea, imo, but the base concept of the spell as an AOE DoT I don't necessarily have an issue with.
Plegma - WHY ON EARTH did you keep the near melee range on this thing after changing Dyskrasia? And I'm against the increases target damage taken by 10%, because that runs us into the same "too many debuffs" thing. If it's going to be a debuff on a target/targets, it should affect all party member damage to them. If not, it should just be a self-upkeep buff like Storm's Eye.
Polydipsia - Selfish Pneuma? That is, only applying to the Kardia target? I don't have a problem with this (Soteria as its own button is silly anyway), though it seems......I dunno, can't put my finger on it, so I'll say I'm fine with it for the time being.
Eukrasia version - Makes an AOE instead for two casts. I'd rather THAT be a separate button not tied to an attack, but I also don't mind this too much since I think the kit should have more Kardia interaction including a way to AOE heal with it. I'm just not sure two 170 heals is sufficient for that, but...
Bia I have no issue with other than it seeming weird to me for some reason. I think Zoe as its own ability makes more sense, but my bigger issue with Zoe is that it only works on ONE ability (same issue I have with Thin Air). This doesn't fix that problem, it just makes it more clunky. Maybe have it be for the next 2-4 heals or a 10 sec duration instead, I dunno.
Eu Bia, on the other hand, I don't like at all. This is SB Lily (initial incarnation)/Aetherflow all over again, and I didn't like the mechanic then, either. Granted, in WHM's case it was just part of a host of other problems. This is especially bad if we have 2 min meta still, though less so if we don't. In general, I don't think that abilities like that should work this way. I think Rhizomata is a far better button for that as it works. If this just flat generated an Addersgall, that might be better, but it has no CD and you've removed most MP costs from everything else, making it spamable, so that could be bad.
Katarrh - Why? That said, I all the time say Plegma should be a 20 sec CD instead of 40 sec. BUT, it also needs to be GCD so it can break up the Dosis spam. Making this oGCD seems bad. I feel like it should be a GCD instead and just do Dosis + 140 potency instead. Better that way. Make it a shorter CD Plegma so players can break up the GCD chain more, and the charges prevent the issue of worrying about delaying it a second or two.
Aside: You have Anamnesis listed further below, had to scroll some to even find it. WHY are there two... ...I'll get back to that. But for this moment, Eu Anamnesis does a 15 yard circle AOE. That'll be important in a moment.
Dyskrasia - Ugh. Okay...hm. So I don't hate this idea - it's Continuation, and I don't hate that - but good god, I dislike the scattered pattern AOEs. I never hated Overpower being a cone on Warrior. I hated Mythril Tempest being a circle. It should have been made a cone instead. SGE isn't a Melee DPSer. So maneuvering around the enemy to swap between AOE pattern types doesn't have the gameplay advantage it would on, say, SMN (I honestly still hate they changed the two seal thing into a circle, the cone was way cooler). I think like with WAR, the 1-2 these generate should be unified in AOE type. So if Plegma is a cone, Edema should be a cone. If Plegma is a near-melee range circle, Edema should be a near-melee range circle. If Euskrasian Anamnesis has a 0 yard range and 15 yalm radius, so should Somnia, not the 25 y range and 5 y radius. Likewise Toxicon has a 25 y range and 5 y radius, so Anathema should as well.
Right now, you have Plegma's "combo" as a cone (which is CLOSE ENOUGH given what Plegma is), but you have Somnia and Anathema swapped from what they should be. Why would you use a 0 y range 15 y radius after a 25 y range 5 y radius ability? Why would you use a 25 y range 5 y radius ability after a 0 y range 15 y radius ability? Just unify those together to where like leads into like. That'd be like if GNB Hypervelocity (single target Continuation) was a continuation from Fated Circle (AOE gauge spender) and if Burst Strike (single target gauge spender) had a continuation that was an AOE. It just doesn't make sense and would probably not be fun for most players in general, as well as inject a lot of unnecessary anti-intuitive mechanic for no really good reason.
I kind of like where you're going with Proto-Pneuma and Pneuma, though all this really does is "how can we make Pneuma more clunky and unresponsive?" I'd put the heal on the first one instead and have the second one as just a fun "kaboom" damage ability.
Holos is now a worse Assize. Thanks I hate it. Kudos on giving it 1 charges, though; Assize could use that. And it's a GCD now. No no no. I like Holos' PRESENT form far better, thank you muchly. I honestly think I get what you're going for at this point - making MP the resource you manage for heals, and trying to have GCD heals be damage neutral while granting various effects. I just REALLY happen to like current Holos and would really dislike this being what it became. That said, doing this with Assize I'd probably not mind much at all provided WHM's MP economy was balanced around it.
Ah, Anamnesis...why? Why is there a base version? The Eukrasian version is literally better in every way, so you'd never use the base version. The only think I can think of is you want the base version to be a way to generate Addersting, I guess...but you could just do that with the AOE damage version and call it a day. This seems to be a bit more a case of clunk for the sake of clunk than meaningful decision. Your options are use base Anamnesis into Toxicon into Anathema or Eukrasian Anamnesis into Somnia. But they both do the same damage, so the only question there would be if you wanted an AOE sleep or wanted AOE magic reduction damage, I suppose. But you could just get there by using a Eukrasia heal then Toxicon then Anathema anyway. I just...I see this as more unnecessarily clunky than generating meaningful choice in most cases. Especially since you'll probably be using Eu Anamnesis every 15ish seconds (or whatever you feel you need) anyway to keep the refresh up. As Toxicon isn't a damage gain here, just a mitigation gain, you'd just sit on Addersting charges until you needed it and would rather generate them in general by using Eu Diagnosis/Prognosis anyway while refreshing Anamnesis via Eukrasian Anamnesis.
.
I dunno, some good ideas, some a bit convoluted ideas that are still okay, and some unnecessary clunk.
I'd combine Anamnesis and Eukrasian Anamnesis into a single ability, change Zoe to be a short duration effect, unify the AOE shape/profiles of the Continuation effects, give Plegma a 25y range, put the heal on the up-front Proto-Pneuma, remove Eukrasian Bia, give Soma a damage reduction, leave Holos as it is today, and remove the CD from Kardia.
.
While that DOES sound like a lot...honestly, the rest of your idea I somewhat like a lot of. So...
...consider this critical, but not antagonistic feedback. While I mentioned 9 things here (which seems like a lot), I like the core of what you've created and how it works for the most part. So kudos on that, not bad at all, my man.
.
EDIT2:
Ugh, HOWEVER, so we can ruin this otherwise feel good moment...
Past need not be prologue, especially since "add more attack" is already the opposite direction they've been taking Healers. ESPECIALLY since we agree Healer kits are already a little bloated (your SGE rework is partly addressing that) and that things like ability upgrades or charges, etc, could be an effective answer, and that the continued additions also sometimes lead to un-creative "checking a box" additions, such as Aquaveil/Exaltation/Protraction (at least one of these was probably a "Well, we're giving the OTHER Healers 2 actions...so how can we make this JUST different enough it doesn't seem lazy?")
And while I suspect you think you were doing it "for my benefit" (I'm not sure I believe that, but for the sake of argument I'll give you the benefit of the doubt), the problem is that you are ASSUMING everyone who doesn't want new actions will select Other instead of just the first option on the list. Secondarily, the question allows multiple answers, so for example, someone could click all of them at the same time. In neither case does that support the "leave things alone" side of the coin.
