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

[Jandor]

I mean, again, his mindset is clearly different than what it is in Elpis, so much so hes shocked at what he becomes. The fact is with everything we're told and shown, had Venat actually told her people what happened, they could've found a way forward, they just werent given the chance. Considering we have relied upon said unsundered ancients time and time again, we clearly cant do it ourselves. We need their help. If we couldnt do it without their help then whose to say they couldnt do it themselves? Dont take this personally but i think the writer's wrote themselves into a corner with this and it shows. While trying to write the story in a way that indirectly tried to say the sundering isnt all that bad and the sundered are capable of things the ancients arent, they contradicted themselves based on how theyve wrote things in the past. The sundered have hardly ever done thing via their own merit. Theyve done so with indirect help of the ancients or higher up entities. Hydaelyn,allag, etc etc. It just shows we'd be nowhere were it not for them.

Cute, but irrelevant. The story is what the story is, you don't have to like it, but wishing it was different doesn't actually make it so.

The Ancients couldn't win, you're outright told that. I would have personally preferred that it be reinforced with a little more explicit showing along the way, but they decided to go with mainly just telling us, and I struggle to think of a way they could have more explicitly told us without just breaking the 4th wall and literally telling us.
