@Bardoly:
I had a thought about Heavy Bombers, since so mant people seem to think that the tech is broken.
Why not let them be a 5 on Attack, a 2 on Defense, and their SBRs be an automatic “5”.
Never defense at 2 bombers were never meant for defensive purposes and thats why the the bomber gos 6 (that way you can hide behind a line annd still attack with the fighter(s)who are hiding behind another line!
