I'm hoping for more of a character-centric season, with more development for our secondary characters (particularly Celestia, Luna, and Cadence) as well as our mane cast. Less new characters and more expansion on the ones we know and love (or, in some cases, love to hate). Overarching plot themes aren't that important to me, but a theme that carries over 2 or 3 episodes might be a nice change.
Agreed, and that might also mean more development for *gulps* Flash Sentry. I would really like that, because really, his only flaw is his lack of character. Now if you'll excuse me, I need to leave. I see an angry mob coming.
