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

[KageTokage]

I was really looking forward to the truths we'd learn about the time of the Ancients amounting to more then "Almost everything happened because we're stuck in a causal loop"; that their society was definitively heading in an unsustainable direction that warranted the sundering and the fact that it made us capable of fighting Meteion more of a happy coincidence then something that had been planned all along.

A miraculously preserved present day Elpis that told its tales of the past via Echo visions and ancient records could've still fulfilled its needed purpose in the narrative of isolating the source of the Final Days with the only real loss being that we wouldn't have been able to spend any personal time with the Ancients.
