I feel that weapons in general should have a quicker reload and lower damage (to maintain dps) as standalone systems. Not by too much, maybe drop from an average 3s reload to 1 or 2. As it is, I feel like I need at least 50% cannon slaves on absolutely everything in order to have a decent reload rate, which eliminates the use of any other slave weapon system, so my weapons aren't as specialized or as effective as I'd like. On the other hand, having weapon combos that increase damage should increase damage by even more and make the reload time longer (maintaining dps), all to keep the "epic" feel of the combo.
I also feel that beams should have a range of 80% that of cannons instead of 50%. (800 m) A range of 500 m just seems too nerfy, even for an instant hitscan weapon.
I'd also like to see slaved single-weapon computers that can be slaved to a weapon system that (similar to light blocks) can be linked up to give the "look" of the weapon. For example, you slave a solitary cannon computer to a weapon system, to make the weapon system fire small "bullets". Or slave a solitary beam computer to a weapon system to make the weapon system fire "blasters" (elongated bullets/lasers). Or slave a solitary missile computer to a weapon system to make it fire larger (and maybe slower?) "bullets".
