If you could add 1 thing?

[OrganizationXIll]

Removal of all FATE's or a heavy nerf to the xp it gives.

Or buff to everything else? I don't want to take 2 months to get to 50 on subclasses. >.>

Greater interaction with the environment.

(Be able to steer-jump, swim, no more invisible walls, no glowing lights to represent everything, hidden path that require a bit of jumping and thoughts, etc.)

No invisible walls, but you want hidden paths you have to mountain goat your way up. Nice.
