If we’re talking about healing spells natively being DPS neutral, than yes it creates an apathetic loop devoid of skill expression, but if DPS neutral healing is something you earn by the decisions you make with your kit and your resources, than I disagree that that’s an issue.

In my white mage redesign for example, I reverted the system back to the lilies and blood lily, and Holy III became a cooldown that granted Sanctity. Sanctity was spent on one of two DPS options with different supportive qualities, and spending those would allow Cure, Medica, and a GCD Aquaveil to nourish the blood lily. As well as Esuna III under Assize’s effect. But I also allowed Holy III to be castable off-cooldown at double its MP cost so if you want every GCD heal to be DPS neutral than you can burn your MP to do so, and I think that’s a choice that feels interesting.
