What's the point with that quite lackluster story in Endwalker?

[CrownySuccubus]

It’s less they had to go because they didn’t suffer enough and more that they couldn’t cope with suffering and move on.

In this case, it's the same thing.

As I said, the writers were trying to convey the idea that a life without suffering is either impossible or delusional. That's the entire reason we see the Ancients during the Final Days panicking and longing to go back to the way things were. The argument is that, without a life of suffering to make them "stronger", the Ancients were ill-prepared for when it finally came. Thus, they were doomed to fall into even more delusional and blissfully-ignorant dreams of "utopia" if they ever got their paradise back.

I could spend all day unpacking the faults with this philosophy, why it doesn't quite work as the writers intended, and why it's potentially harmful, but my point at the moment is just to explain why, to the story's logic, the Ancients were painted as "delusional".
