While i dont want them to "vanish" from the story 100% I think they need to take a step back, I want a new cast of characters who can get development, I feel like Endwalker was a good way to send off the scions.

Also a scion "dying" is usually some sort of fake out most of the time, which makes us have no real stakes with them anymore because you know they're always going to be fine, even if they happened to go off that way, no one would take it seriously at this point.

Personally I felt like a lot of the scions should have took a step back and played smaller roles in the story. But It looks like they're going to be a main part of it.
