Yeah, a villian that is deep and thought out would be a nice addition. Something like Typhon or maybe a Stallion with an agenda of their own. Somepony risking the lives of the Mane Six or others in an attempt to get something they lost or doing a 180 on their initial personality. Some Pony action would be nice, maybe some romance, suitable for kids romance. I'd like to see Rainbow use a wing weapon. No death, Id hate to see Fluttershy ever get hurt or lose any pony. Maybe the real villian is Celestia? That would be a twist...
