I think the only thing squadrons need is to be able to activate like ships. It should be a blanket "You may activate one ship, or two squadrons". Because lowering your fleet activation count in order to include squadrons is pretty painful, especially if your opponent is the first player.
This is the biggest draw back to fighters. But it's also what balances them. A few bombers can sway a battle decisively... A command dial, hit the adjacent hull zones to kill the shields, and then have ypur VSD I unload a full front barrage into the center location with ACMs and there is two hull from the ACMs plus whatever gets through shields from a potential 12 hit shot.
