Problem with that is: I've added Large-Scale Gatling Cannons and Heavy Vulcan Autocannons that fire really fast... will do the supply thing tho, but remember: projectiles are relatively weak in comparison to energy weaps (especially anti-capship weaponry... 1K consistent damage on a range of approx. seven. OMFG) and you still have torps to take up the middle.
So the basic weapon usage layout would be:
-Early game: Projectile, perhaps early Torps, perhaps early Beams
-Middle game: Projectile, Torps, stronger Beams
-Late game: advanced Projectile, minor usage of Torps and large-scale Beam weapon deployment
Still a [censored] pity of the GC...

realy wanted to add that Artillery. Oh well. Back to the drawing board then. Will have to make the Artillery space-based long-range heavy weaponry...
