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

[Cach]

Nothing within that point of the story is related to Final Days or Blasphemy phenomena, other than, "Oh hey, we know the root cause, so now we gotta rig up this spaceship!" Idk, it just felt like there was very little tension.

Before the spaceship takes off, they do the "everyone gets together" thing, but they previously did that before the Garlemald expedition.
"Oh we doing this again, uh" the scene didn't work for me that second time.
