i think it would be good if a weight system is implemented where each weapon has its own weight, taking into account the weight of ammo too.
this will prevent people from Loading up on TNT and explosives, at the moment this does slow you down a bit, however like TCatPlaysGamezYT mentioned, this can just be counteracted by pulling out your knife and running at full speed again.
the system might already be there, but i think it might need a bit of reworking.
I like the idea as is you can add up to three grenades, or three more med packs or three more ammo packs, imagine running the map with a group of ninja rocking daggers pistols and smoke grenades, or a group of heavy gunners with plenty of ammo and health packs, or a fire team with flamers and Molotov’s
