I am going to pull a leg here...
what if, there's some kind of benefit when strikecrafts battle near their carrier due to, let's say, easier coordination?
for example, there's a game where drones benefit from battling near their hosts by being able to change targets once their initial targets is destroyed.
That way, we would have some KIND of incentive to attach the carriers to the main fleet, instead of camping outside the gravity well, jumping out at a moments' notice.
