When I heard that line ("Epic pony war") I knew, inmediatly, that there was some kind of joke I could make.
My god, I'm bad at making jokes. Please don't hate me.
Who are they fighting? Changelings. Why is everypony wearing armor but Twilight, who's wearing spandex?
Well... when you work five hours a day just for the sake of having a good plot, you show it, goddamnit. And spandex looks perfect on Twily's... flank.
Also, rule of cool.
