How about you just make it like it was in year one where everyone spawns with ammo. Rather than ruining your own competitive game type by forcing a specific meta, rather then letting people play the way they want. To me, it sounds like you want people to not play competitive because you don't give a damn.

they wouldnt have to try and force the use of something if players would just stop relying on insta-kill methods, yeah its smarter to use but as we all see, it has destroyed this game.
