Consequences Doesn't Necessarily Mean Death

[Jeeqbit]

The changes to the scions in ARR were mainly to differentiate them, if you think about it. They were all kinda the same until that happened.

Thancred became a person who had to focus on physical fighting and physical skills. Y'shtola's desire to overcome her blindness gained her a super power in seeing just aether. Urianger was already the scholar/book person. Yda was also a physical fighter but they gave her an actual backstory. Minfilia was pushed out of the story because they wanted to replace her with Alisaie and Alphinaud. And they couldn't salvage the others.

And they have given new characters interesting things (Estinien's connection to nidhogg being somewhat a super power and being a dragoon, Gosetsu being a Samurai and developing injuries along the way).

They haven't really done a lot to further injure or hinder the actual main cast since. I just think this is because they achieved their goal at the end of ARR of transforming them from bland characters that were exactly the same, to people who bring unique attributes to the table. But they have been willing to develop temporary characters that aren't part of the scions, even recently injuring Arenvald and putting Fordola through an ordeal. Most likely Wuk Lamat will have a whole load of development that the scions won't get as well.
