Still sadly the best tactics (rebel or imp) is to upgrade some fighters/bombers, spam-produce them and use all 80 slots for them. No fleet can ignore 80 battle squadrons. If their pop cost is only 1 in battle, starfighter rules.
I would like to see all those little ships upped to pop 2 to be less effective tool. If bringing solo starfighters squadrons into battle is more profitable than on-ships squadron, then, who would produce ships?
PS: I know there is at least one exception: Correlian Corvettes in maxed version bring X-Wing with them. So it's better to produce
CR90 corvettes than X-wings
