Consider, instead, a far more basic class system: heavy, medium, and light classes. As far as who spawns with what, well, that would be a simple. Each of the main three classes would have the sort of effects you could guess. Heavies can take more damage/less speed, mediums are the all around, and lights get a faster movement speed/less health, and etc. From here, each of the three weaponry classes could be divided for long, medium, and close ranges. Let's say, a light class Spartan spawning with a close quarters weapon would be given an SMG, a medium the Assault Rifle, and a heavy the Shotgun. Now, that raises the question, why on earth would you want to spawn with a shotgun on a larger map, but, hey, different strokes for different folks. A mid range spawning group would be, once again in order from light to heavy, an Assault Rifle(WHAT? - Battle Rifle =/= sniping caliber, Assault rifle = Sniping caliber), Battle Rifle, and possibly a turret for heavies. Long range, well, I find this a bit on the hard side to figure out, as heavy weaponry is... Well... Just, rather restricting, as well as what should be given at this point. Best guesses would be, once more, light to heavy: Battle Rifle/Sniper rifle, Sniper Rifle, possibly, a deployable variant upon the regular turret. Of course, really, I think changing up the default spawn weaponry causes problems, but, the concept of creating variance in what the Spartan themselves are capable is far better.(You thought no one could make that jump, but guess again! Two light-armored SOB's just flanked your team and wreaked enough havoc for their team to regain control of the situation. You likey? I likey.)
