From what I can read of 1.0, the story elements actually had an impact on the world which is something I would like to see again. The world right now is just so static, even having finished Endwalker I feel like my character and the Scions have had no impact on the world. It's probably a hard sell to change things since you have to account for new players and how they will interact with the environment and progress through the story but it has been done in MMOs before.
