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

[Theodric]

My post was directed at the unnerving people who would kill everyone on the Source and bring back Elpis. We may remember the Ancients but they would never remember us. Not to mention outside of trash fanfiction I'm never going to read, there's no feasible way to get Elpis back without letting the Ancients kill us. Losing Elpis sucked, but I'm not giving up what I accomplished as Egil Vairemont.

Yes, you've made a number of posts expressing such 'concern' from what I recall. I'd be more worried about those who can't grasp that none of the characters are actually real and are simply pixels on a screen designed to entertain us at the end of the day. Just because someone joins the Dark Brotherhood in an Elder Scrolls game that doesn't suddenly make them a mass murderer after all. Though in my experience, those who express concern over someone's stability in regards to a video game simply aren't coming to a debate in good faith.

As for the Unsundered world continuing to exist? Well, Shadowbringers already established the existence of alternate universes to justify G'raha Tia's continued existence. The writers may not have gone with the same approach for the Ancients though it's not like it would have been impossible for them to have come up with a way to do so.

We can also look at the single player games and note that the draw for many lies not only in the story of the protagonists but that of the antagonists. A one sided approach where the protagonists gain everything and the antagonists lose everything isn't what a lot of us enjoy...nor was it ever the core premise of FFXIV back when it first launched.
