A lot of the main issues with SCH are not being addressed with Endwalker

[GrimGale]

Players just don't want to spend the iota of brain resources it requires to make decisions on the fly in their healer gameplay. There's just no point arguing with these players and SE will acquiesce to them eventually.

"I don't want any decision making in my healer gameplay and want to just play the same rote way every time so I can zone out and collect my tomestones" - most of this thread

If decision making is choosing between using a heal and dealing damage then no, that is barely decision making, especially when you can keep people alive just by using Fairy abilities, that require no AF and do not waste a GCD.

The problem with ED is that it becomes a significant DPS gain and completely turns Dissipation into a dps boost.

If you make players chose between using resources for healing or dps, then you give them free abilities that lets them heal at no cost, you'll see them blow all of those resources foe dp, as healing has very little value in this game.

By that token, though, anything that isn't yet necessary in a given piece of content cannot constitute decision-making.

If even in Savage there's no point where Aetherflow heals wouldn't be a "waste", causing Energy Drain to be "barely decision making", then we've got a much larger problem than just Energy Drain being a contextually unnecessary convolution. (Though, all rotation beyond Glare/Holy spam also fits that definition.)

See above.

Isn't that equally an issue of Dissipation's design, then?

300 potency that you gain from dissipation if you burned every single charge on ED is not a "significant DPS gain". It's essentially an extra broil every 3 min

With as nerfed as it is now and with the MP removal of it, Energy Drain pretty much has very little use anymore.
