Anecdotal feedback is what it is, but I'd rather have reliable snappy skills than fairy skills oriented on its positioning and movement any day of the week. For every single piece of opinion information there will always be a counter. That's why it's not the full crux of my argument but just a single aspect.
Also we're not talking about the entire kit becoming like SGE's, we're talking about ED and small adjustments to the class and/or its fairy/ogcd kit that will make it feel better to use (which again is player preference sure).
I'm not saying copy everything from SGE's kit but there has to be some middle ground between "Fuck it make them all the same" and "LEAVE IT HOW IT IS" and I'm looking for that. Instead of just saying "That sucks because it's like SGE" why not spitball other options or maybe go back and forth on further iterations to the kit? Why not provide feedback on what you'd like to do with ED that makes it worth leaving on AF when everyone will always choose damage over heals when/where they can for the most part?
I love SGE and will continue to play SGE but it doesn't mean I want SCH's to kick rocks and screw themselves. I want to discuss the kits after seeing SGE and new SMN and I think there's room to grow the kit that isn't some outdated premise of "Aetherflow needs to be on AF so I don't cap" or something new could be done with Aetherflow in general.
As for AF heals, I'm totally fine with SCH having a buff to its AF heals as one of my preferred changes would be to have a skill or skills on AF that actually provide shielding so they're slinging barriers more often (not OP but just more than one GCD worth/Seraph).
tl;dr We can do more with ED than keep it on AF "Just cuz" despite some weird idea of it being "rewarding" gameplay to that person, and the fairy and fey skills can be used to better add distance between SCH's kit and SGE's.
EDIT: To add some context, perhaps if the fairy were more responsive/snappier like the summons you could seamlessly transition between Selene and Eos to provide differing buffs and utility to the party like the SCH used to. I'm just saying we have options we could explore.
