I saw on another server, that on specific map only specific weapons can be used (in that case it was dressing room with pistols and knifes only). So i thought, if you can, that we "ban" some weapons from some maps. Everyone knows how irritating it can be on blue team in uptown when read team smokes and grenades. You can't get out with 100% health. Or what can grenades (all types) do in dressing room?
I don't say some weapons should be totally banned from all maps, but there are some maps that aren't "suited" for some weapons. Even smokes can be used wisely and tactically (something like comsa) but people mostly toss them to ruin gameplay. Same goes for HK69.
