Pointing out some things that seemed to have not connected with people.
Confession: as currently known with th relatively short buff duration, may be hard to use/track i have nithing to counter this part with.
Cure 1/2 Spam Procs: so lets see currently spamming these will give you, chance to save MP on a heal, charge a low ogcd heal on a target, and stack an OGCD spell CD reduction. While each point of RNG may very, you get quite a lot out of it. Also AST gets hit with a similar function on Benefic 1/2 for reducing the GCD on Lightspeed with crits, so the crit RNG directly applies, and a chance to crit with Benefic 2, so basically a big (usually overheal) with a guaranteed CD reduc proc.
Compare Gauge to Gauge: complaints about comparing lilies to ast cards... Um have you looked at the AST gauge, it has like 4 things on it... All related to our cards.
AST Getting Healing Magic Potency on Diurnal: were also losing the spell speed on it, and 10% has always been there on noct, so mild buff. Both WHM regens are natively stronger. Also WHM Medica 2 has the widest radius of any healer aoe heal by 5y, and with how big bosses get, thats a huge issue SCHs and ASTs have to watch for.
Esuna: Negated, all 3 are hit by it.
Lucid Dreaming: SCH made out like a bandit here, AST and WHM both got hit tho. AST gained enmity reduction, WHM gained duration out of this.
Largesse: Not sure if Dissipation was removed for this, but Synastry was as well (honestly I expected this to be XRS synastry when the Divine Seal is gone rage began). Albiet I used synastry for the extra heal target not the bonus healing, still im assuming some ASTs did care about the 20% healing bonus.
Direct Damage: Stone IV, Boil II, Malefic III i dont think this point matters, going to cancel out for the most part.
DoTs Loss: SCH is losing at least 2, WHM/AST are losing 1 each as far as I can tell, also kindof cancels out.
Lilies vs Spear: In the ideal world of nothing preventing an AST from being able to use it, comparable. But unless some changes to how Royal Road activates happen, even if our odds of having it are 4% better, your odds of being able to use the lillies is 100%, ASTs and Spear, hard to calculate, but at best, maybe 20-30%.
Our Stuff is Tied to RNG: Understandable until you make it seem negative compared to AST whos core component is based on it. We even have 3 buttons dedicated to mitigating the RNG of the system, were getting another, and a button to make it easier to deal with when we fail... So if you include the draw, we have to manage 6 buttons to accomodate the natural RNG of our core mechanic.
Stoneskin is Gone: from what it seems tanks got a version of it, and some is tied into other WHM stuff. Not much to comment here.
Protect Moving to XRS: pretty much everyone is getting hit by this type of thing, SCH got hit with it as well in the case of Virus and Eye for an Eye, they can get half of Virus back the same way and all of E4E.
No DMG on Fluid Aura: all OGCD CC in the game got this treatment, and it was long overdue. These skills being used for DMG pretty much killed the ability to use CC in game. IMHO good riddance for all of it.
Lack of Extra Utility: Bit concerning, cant lie, but on the other hand, this means you can pretty much dedicate to DPS once your caught up.
Efficiency: WHM looks like its going to retain being the most MP efficiency healer in the game from what I can tell, SCH is maintaining having the easiest to regain MP. ASTs still in 3rd here, tho lightspeed being used more for its cost reduction purposes seems to be something thats getting advocated in 4.X. Wonder how long it will take people to realize Cure I, Physick, and Benefic I plain casted are the most MP efficient heals in the game. Maybe 4.X will finally make players here realize the value of MP efficiency instead of pure throughput.
AoE DPS: SCH lost here, mostly because it has to play on the same playing field as the others now.
Group Composition Demerits: WHM still wins here. WHM/WHM is still the easiest on the player. SCH/SCH is the worst. AST/AST changes based on sect preference of the player, it can be fine or one gets screwed, same with AST/SCH in the case where the AST prefers Noct Sect. Imagine a world where 2 WHMs couldnt stack Medica 2 in PvE. Yep, itd suck. Rest of us live it.
Being Ignored; Facets of RNG: RNG has 2 main points to it, chance of occurance and chance of desired outcome. WHM range is completely chance of occurance, which means as long as it happens, you have. 100% chance of the desired outcome. On the flip side AST has a 100% chance of occurance with a a ~16-17% chance of desired outcome for usage, and a ~32-34% chance of desire outcome for holding. Essential difference here being, if our chance of desired outcome is equal to your chance of occurance are remotely equal, your odds of getting what you want are vastly higher, given that the outcome cannot fail or be wrong.
Checking back thru to see what I missed.
