Here's an idea. Probably stole it from another game, but who cares.. How about being able to choose certain squadrons/groups of your army, and train them for a specific purpose? Mainly I'm thinking land here, say training Stormtroopers to do certain things, for example training a sniper squad, or a demolitions squad, instead of just having one set type of unit. I realise the Rebels kind of have this, but even then it could be improved, with their skills improving and the unit growing and becoming stronger. And another idea (I'm freeforming here, can you tell??) would be being able to mix and match your elite units, so you'd have one great squad which would eventually grow and be a hero unit, with morale boosts to other troops it fights alongside etc. as it has become famous. I realise this would probably be very hard to put in a game, but would it not be extremely cool to train your own Wraith Squadron- or Delta Squad-esque group? Please don't flame me for this, as I realise it's almost definately a fantasy. Still, one can dream..
