I did a search i didnt see any suggestions reguarding this. But having only 2 firing subgroups before you have to switch to a new group is frustrating. most people playing this game and games in general have atleast 3 button mice.. mine has 7 and that low in comparison. or if you are using a joystick you have a crapload of buttons you can assign functions to. So my suggestion is to have atleast 5 fire sub groups per weapon group. in ships with 6 weapons have to switch groups mid combat is a waste of time and can get you killed because you have to cycle groups and if you screw up you are wasting a lot of time. on my viper with 4 weapons i should be able to assign 2x multi-guns to 1 2x plasma launchers to 2 and have my kill warrant scanner set to 3.
