As I've said elsewhere, Endwalker is the "Final Disc" of the FFXIV story. It's the "Hero's Return" portion of the tale where said heroes apply what they've learned into overcoming whatever the final adversary of the plot is. Sure, more dire stakes would have been cool, but it didn't make or break the arc. However, with that said, the reason the problem is so pronounced is because of the constant fake-outs. If you're not going to kill anyone in the main cast, then fine.....but stop trying to pretend that you might.
But that hadn't even happened yet, by that point in the story.
