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

Sorry man, but I have to be honest with you. While I don't think the developers have actual ill-will against those who want to see healer changes--I do think they actively ignore us and have made this pure healing boring crap their sacred cow. Meaning, they'll never change it no matter how many people complain, stop playing healers, and/or post on the forums. We're stuck with this garbage 1-button spam for a long, long time.

This actually is exactly why the healers are like this now. Back in Heavensward we had a bunch of healers whining that they only wanted to heal and do absolutely no DPS what so ever. Yoshi P agreed that this was okay and thus things got adjusted to push that tanks and healers are much more minimal on priority to DPS. This also killed a lot of DPS for most of those classes. DoTs being changed after Heavensward also might be arguably one of the big losses classes as before those DoTs were a major part of your DPS and melting mobs. After HW they wanted to remove most of the DoTs. In terms a lot of other changes happened like DRG not having high physical defense and HP with tank buffs and low magical defense as well as many classes losing the ability to have skills from other roles not of their of class.

Though in terms the healer only priority is stemmed from a complaint of lazy healers back in HW where they only wanted to heal and do no DPS and Yoshi P agreed upon this. Probably pushing for an anti-toxic community and trying to address even unreasonable complaints. DPS checkers also were something they didn't want because of targeting players as an example and we also lost the ability to skip cut scenes in Main Scenario Roulette due to complaints which now just makes people not want to run Main Scenario Roulettes either. It also removed the ability to chat in Feast due to not wanting toxic gameplay. Unfortunately Feast is much better prioritized with chatting and coordination so it was another flop in the choices they made. Of course Feast is a flop altogether as it's unrewarding and 100 people getting the prizes per data center was a poor choice. Ques never happen asides from cheaters manipulating wins for the prizes. These terrible decisions were also like this for Triple Triad.

Sorry I trailed off but just notably you are correct and that's why it's like this.
