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

[Nebelheim]

What's crazy to me is that they apparently wanted to rush it because they weren't sure if they'd get another expansion to tell it or whatever their excuse was.

Yet here we are with rumors that Yawntrail will be a filler expansion.

We wouldn't need filler expansion if you'd just done 6.0 as a real, not rushed, bridge the story properly expansion...

I think they originally had it set up for 6.0 to be a garlemald expansion and exploring more of ilsabard and face off against possibly zodiark during the post patches then 7.0 focus on hydaelyn and endsinger and everything else. But they decided to wrap up the long storyline instead in endwalkers instead of continuing longer.
