I don't see how "bombers" can be effective against ships. My last game was against Tarkin and 3 VSDs. I had 6 squadrons and the biggest problem was positioning my squadrons for an attack. WIthout a Squadron command they had to spend a round just MOVING, and not attacking.
Because of Tarkin, and the 4 engineering. I had to do more then 3 shields, or 2 damage, to gain anything. Luke is likely the most effective solo bomber in the game because of his black dice, brace defense token, and the ability to ignore shields.
By the end of round 6, one VSD had lost all it's shields, but had no damage. I just don't see how fighters can even take down a VSD by themselves.
