The Death Scythe heavy fighter has a Cruise-Disruptor only slot, and a torpedo/CD slot. It's a nice setup, since the whole reason for bombers to have 2 CD/Torp slots is so that they can disrupt the enemy while still having the power of the supernova for taking out caps/transports.
The problem with the death scythe is that it doesnt have enough energy to fire even a mini razor/inferno from it's torp slot.
If we got some mk2 heavy fighters (as you put it "light bombers") that had 1 CD slot + 1 Torp slot, and enough energy/energy regen to fire mini razors / infernos / nova torpedoes, they might be worth using. Their standard weaponry can be topped off below VHF's to balance things out - give them 2 class 9's, 2 class 8's, and 2 class 7's or something around there, or even 4 class 8's + 2 class 7's.
