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

Ah, so your problem is that the Ancients didn't suffer enough in death? Would it have been more acceptable if they had chosen to fling themselves into a pit of vicious monsters instead of choosing when and where they wished to pass on peacefully?

Weird take away, but no. My issue is them literally throwing away their lives prior to calamity, via self termination. Furthermore, the fact this irony that the Unsundered long so for their loved ones and the lives they had prior when they used to do this flies over so many people's head in these arguments is frustrating.
