Cure 3 is perhaps my least used WHM ability so that sure is one leg WHM has over AST.
Not to mention it being just 200 potency stronger than Medica & having a really abyssmal range is really weak for a unique gimmick. You can use Afflatus Rapture coupled with Plenary and not only are you healing the same amount as Cure 3 without Plenary but also lose less DPS and MP.
Casting four Cure 3's during a plenary window is 6000 MP and Thin air can only halve that, good luck weaving it tho because Cure 3 cast time is too long, preventing you from not clipping.
The only reasons these buttons exist on my hotbar at all is because I macro'd them together with Lilies & abilities they should upgrade into. ARR throwback time:
The macro works as follows:
If I have Lilies, Afflatus is casted
If I don't have lilies, Cure 2 is casted
If I have neither (e.g. Sastasha), Cure 1 is casted
Same with Medica & Afflatus Rupture.
Disclaimer: These macros aren't optimal as they aren't getting the same GCD queue system as non-macro'd Abilities, I just do this to have a clean UI.
The choice of going 310 potency & 1000 MP negative vs going 110 potency & 0 MP negative? What kinda choice is that?
And the alternative of using Lilies as little as humanly possible to not lose too much DPS is better? Healing on Sage & Astro doesn't cost you DPS, both have powerful oGCD that don't penalize for doing your job.
inb4 "But I always heal with GCD heals and Lillies" then you're just not playing optimally, which is fine if you don't but this doesn't make the argument from people who do care about optimal play less valid.
Don't worry, people are complaining about it and this issue was fixed before Endwalker released but cropped back up again.
