cool idea but ccnet is set in the first world war so something akin to a 70s smg like the hk mk5 would be out of the question. on ccnet guns take a very support-like role. people either use guns to support kills- (the mannlicher), prevent banner caps with high damage (the springfield or gewehr), or outright get kills with any mid-ranged to long-ranged rifles.(sorta like a vulture). i see smgs & ars falling into that last category. a debuff for these new guns like slowness would have to be warranted in order to give melee pvpers a fair chance to take these players down imo.

1. The setting is easily interchangeable as guns had a pretty similar role in the 70s as they have now. They just had different ones.
2. Some ARs and MPs would be short range weapons. I could see some kind of disruption effect to be a good way to balance them. Example: Your fire gets halted for half a second after being struck by a melee attack. That way Guns could reasonably put DPS swords without being oppressive

i agree! this seems to be a pretty good idea.
