- True 3d battles - e.g. a flying unit shouldn't have to worry about units which don't have ranged weapons or magic, attacking uphill should be harder, some spell effects should flow downhill, etc.

- More targeting options. Just about every army in the history of time has recognized the value of targeting enemy commanders - it'd be cool if my archers and magic Users could do so as well.

- Combined-arms options - e.g. attack after this spell is successfully cast, attack the targeted units from multiple sides (which would be very useful with flying troops), or things like "follow behind the heavy cavalry" so you have a better way of dealing with different unit speeds. In particular I've been annoyed when storming castles when some units spend the entire battle trying to get in through the walls rather than the congested entrance.

- The ability to disband units. It'd be handy if you could automatically discharge any unit with certain wounds or simply do something with all those militia when you're in a low-supply province.
