Isn't that what the Dart is?
A dart with single missiles greater range speed and tracking and less ammo. Note that the amount fired at a second would be lower despite the higher firing rate. It was originally thought up for the gtva in retail freespace.
Concerning Ideas:
I think we have too many fighters with two medium sized gunbanks and two medium sized missile banks.
Ideas would be:
Secondary sizes in tornadoes.
Keep in mind that the numbers are meant to balance in retail fs2 and not in WIH so you would need accordingly higher numbers. (I think gunpoint-creep and secondary-capacity-creep can be a problem)
laser: 1,2,3 secondary: 80,16 Theres always use for a single stiletto or a small amount of tempests.
laser: 6,1 secondary: 16,16 High fire power, but you can choose only one main weapon. choose subach for bomber intercept or kayser for dogfighting. The single one could be something like a maxim for bomb interception and as a finisher, or a circe or akheton. (insert random fed weapon) This is a primary weapon ship, interceptor like, really agile, but weakly armored. Gameplay is mainly knowing when to strike. You spend most of the time dodging.
