I wish you could have some of the weapons in campaign (i.e Stinger or M4 SOPHM (i think thats what its called) and some of the camos in campaign (i.e on a mission you get an m21 with this really cool greenish colored camo and no its not woodland)
how about some perks that might acually happen without people complaining
steady arm less recoil when shooting (takes up perk 1 and double tap cancels out the effect)
tracer rounds becomes one hit kills but drops clip size and ammo greatly (bandolier won't work with this perk)
supression silences any gun that can't have the silencer attachment lmgs and shotguns for example (not full silence but a lighter colored dot appears on radar when shooting )
there three good perks that all have there limits so they won't become extremly over powered by other combos
