"Bomber: A fighter flight with the bomber trait is specifically designed to attack opposing starships. Because of this, it is unable to make attacks on enemy fighters."
What if the bomber flight is itself attacked by fighters?
Even in WW1 bombers had some machine guns (The very same guns as installed in the fighters) so do the bombers get a shot back?
A fair way would be:-
If attacked by enemy fighters bombers only hit on a 6.
Fighters attacking bombers add 1 to hit die.
Thoughts?
