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

I'd have to disagree on her not having an impact for the WoL. It was her idea to use white auricite to beat the ascians. An idea we continued to use every time we fought them. Sure her time was short lived on screen and imo it's a damn shame because she popped in and instantly stole the show, at least for me.

I do agree though for the wrest of your points though. They really should show more than tell.
