I suppose there is a difference between World-building and exposition. Exposition is establishing how the world and characters work so you don't feel lost (yeah, RT? That Dust/Aura/Semblance episodes would be real nice), but world-building is stuff that just gives it more depth and explanation. It isn't necessary, but it makes it a hell of a lot more awesome.
