-- So, off the cuff idea for Meson Cannons.
Currently, Meson Cannons larger than 30cm are strictly and progressively worse, since they fire slower and have no damage scaling, thus rendering the range increase worthless.
What if it was altered so that larger Meson Cannons had a higher effective rate of fire by making them more energy efficient per shot as they got bigger?
So unlike Railguns and Gauss Cannons, which fire multiple shots per increment and thus have multiple chances to hit as a result, Meson Cannons would instead fire more often by requiring less capacitors per shot as their caliber increased.
So I'm thinking every three caliber techs or so, a Meson Cannon would gain one extra shot, but without needing more capacitors to do it. So 10cm to 15cm Meson Cannons would have one shot as they currently do. 20cm to 30cm Meson Cannons would have twice as many shots, 35cm to 45cm would have thrice as many, and so on and so forth with each new threshold adding one shot.
Incidentally, High-powered Microwaves have this issue as well, whereby the lack of damage scaling means that HPMs over 30cm are just outright worse.
Also incidentally, this change could be applied to HPMs to make calibers over 30cm no longer useless while still preserving their "Secondary Weapon" flavor.
