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

[Theodric]

For me it was Graha in 5.3 killing elidibus with his stupid speech of “your soul is mine!” Sit down catboy, you’re lucky your a fan favorite or i would’ve turned you into pop rocks myself >_>

It's still weird to me that a throwaway NPC from ARR was elevated into such a prominent position. It really makes me think where the main story could have gone had it not sought to tie everything back to the Crystal Tower raids...

I'd have much preferred some of Matsuno's contributions to the story to tie in to the finale.
