Removing some scions from the story
Y'shtola, Thancred, Yda and Papalymo are essentially clone of each other, narrative-wise. And it's normal since they come from 1.0 where they were meant to share the same function, except each in a different story line. It was a mistake to just recycle them as-is for ARR, and Minfilia and Alphinaud didn't add much to the dynamic. The result was this redundant group of happy puppets repeating and agreeing to whatever another clone just said. Alphinaud + Ysayle + Estinien was a much more interesting group.
Unfortunately, it's only been temporary, but they're a iota better, now.

Also, unifying the signs/icons during battle.
