We know that Starlight Glimmer only experienced the human world in Mirror Magic, like Princess Twilight Sparkle did in the first Equestria Girls movie and Rainbow Rocks. Some fans might think they have the same reaction after they enter the human world, but according to Dragon Lord Ember's opinion on the two, they do.

There are some other parts of the human world that Starlight never got to experience yet other than the mall; like the city spa, the beach, the Luxe Deluxe, etc. Sunset Shimmer would have at least sent her some pictures of some places she never got to experience and said "Wish you were there." Fans of Equestria Girls wish the same thing; they make fan works of her missed experiences.

Even if Friendship is Magic season 9 is revised, Starlight Glimmer still has so much to learn about the human world like Princess Twilight does. We are asking Hasbro to let Starlight experience more of the human world, even if it is almost similar to Equestria.
