Well, doing this would require IC and Stardock to make unit AI not based on entity. As it is, a ship's AI is chosen whether on not it is a certain type of entity (platform, fighter, frigate, capital), which sucks. So to do that, all ships would need to be strikecraft. And strikecraft can't phase jump. So that, the seeming best method, fails. Add in fighters can't be built by factories, only spawned from ships and you have EPIC FAIL.
I'm not faulting your idea. I love it. It's just Ironclad and Stardock have made awesome, epic space battles so hard to implement. Which sucks. I really want frigates dynamically moving around capitals, circle-strafing in an attempt to dodge fire while cruisers try and stay in its rear arc and blow its engines to hell.
But no. Thank you IC and Stardock, you have made Sins less fun with AI bound to entity types!
