One of the ideas ive seen thrown around was Dissapation temporarily upgrading Eos into a reworked Selene that had upgrades effects to some, if not all, of its spells. While i like that idea I can't help but be fascinated with the fact that instead of reworking Dissapation, they fixed other abilities around it to make it more useable. Personally the only thing i can really think of now is either make Dissapation boost aetherflow heals, either via raw potency or additional effects, or allow us to keep building fairy guage during it.
