I'm thinking that it should work like a simplified Gratuitous Space Battles after playing it. Nice game, but a bit overdone.
You get your ships, you give them orders, then let them at it. No in-battle guidance needed.
One thing I'd like to see from this is to have more variety in types of weapons with the technologies- like point defense lasers that fire quicker for less damage/range, and mauler lasers that are real slow to charge, but are more powerful.
Mass Drivers and Missiles would have their own varieties also, and their own countermeasures. You could make a game within a game of this.
And let's face it, building things to blow up other things is fun.
