My idea is this, pretty much anything you can do with energy weapons is just percentage boosts that affect everything. Beams have their 2 hullmods specifically for them, and everything else will just screw over your small mounts since they'll be outranged by everything. So what if we could get a flat range increase for projectile weapons, that would make AMBs, Ion Cannons and IR Pulse Laser more feasible for ships that aren't running SO. Currently I find myself just using Heavy Blaster and Ion Pulsers in mediums, while small mounts are just PD in 95% of the cases. This way you could actually introduce variety for high tech ships without large mounts.
Following that thought, it should work on ships that have medium energies together with small ones (prerequisite). So that we don't have Scarabs having AMB with more range, and imo that range buff should ONLY affect small energy mounts.
I know there's a Remnant cruiser coming with some built in hullmod that increases projectile weapon range, but that one seems too strong.
Thoughts?
EDIT: Made it clearer I was talking about projectile weapons.
