Despite the significance of the Crystal Empire and constantly visiting it, as well as the Royal Family there being given so much attention in the show, comics, and books, why aren't they full fledged main characters now?
I mean we have Shining Armor, Cadance, Flurry Heart, and Sunburst, we can start to have episodes that just take place in the Crystal Empire instead of Ponyville. I don't see why we don't start developing THEM more.
