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

Okay, so listen. If I break your kneecaps right now and you lose the ability to walk, it's okay because it's not fundamental "to your being". After all, you were born crawling, so if I remove the use of your legs, you should be able to get by just fine crawling under your own again.

Lol for some reason all these talks about whether the sundering is genocide or not somehow reminds me of "First Aid" episode of The Office.

"No arms or legs, do we bother resuscitating them? What kind of quality life do we have there?"

*obviously, this is just a joke. Pls don't take it seriously.

And then there's Hades's stone mentioning "malformed" creatures, which everyone thought was the player races. The life that Zodiark brought before the sundering. Which contradicts Yoshida saying the races developed after the sundering.

I used to think the same. That's why I once asked (not sure if in this thread or at lore forum) if the "new life seeded by zodiark" plays a role in why they wanted to do the third sacrifice.

That aside, I guess my biggest disappointment with sundering is I don't get to truly see the events shortly after it happened. I'm more curious about history and world building rather than seeing venat preaching the players again. I want to see if they lost all their memories or was it just a select few (and the rest were gone simply due to time and mortality). Supposedly they didn't loose all their memories, would they still recognize elidibus, emet, and lahabrea? I want to see how the first generation of the sundered rebuilt their life and society. Were they truly gone back to cavemen level of society and technology? How does 100% hyur like people evolve into different races (honestly though, it's hard to believe a hyur evolve into, say, lalafell)?
