Badger... NPC guns each get their own reticule... each gun works independantly of the main body. That is why they are so accurate... Its basically like having two mouse cursors, one grouped with 600m/s guns, the other grouped with 750m/s guns. Provided you've got three hands, or a mate to help you aim, you can do it to. This is one of the ways in which the NPC's "cheat" because they do things we could never do.
Also, the supernova dps is taken out of context in the instance you describe. Calculate the damage per unit energy used. That is more accurate.
But if you guys think that Fighter fights take too long, do it this way.
15% damage increase to all fighter guns damage.
bomber torpedo weapons unchanged.
10% damage increase to GB weapons.
5% damage increase to Cruiser/destroyer and battleship weapons.
