i think there should be slots like a secondary and a primary slot, so a secondary weapon can only be in the secondary slot and primary in the primary, this way you dont get dual wielding people with 2 guns so they dont have to reload, becuase this gives them an advantage because they can kill you without having to reload

I dont see a problem with people carrying two primaries at the same time... it is nice for surprise-based tactics. Like firing one shot with the m79 at someone hiding, u miss, guy gets out of his hiding spot and starts shooting u, suddenly u get ur second m79 and bang, hes gone :)

Well, I kinda like it. As a server opition, of course. Secondary are nice to have when in a deep spot.
