Epifio does share cooldowns just not if you use it. Other spells put epifio on cooldown AKA mobility spells. The slowness does stay for ascendo I'm p sure appaero just gets rid of slowness in general. I think the fall damage is a bug its been there since pre-rev. It has a low cooldown bc ppl commit a talent to that instead of having better defensive spell cooldowns + its a small heal but, it should have a cast time. The heal is instant so nothing stops it. BASED TAKE, aqua and propulso shouldn't do as much damage as they do. Sorry if my opinion is blunt. Thanks for read <3
