Other than in let's say a specific 1v1 snipers only game what do you think about banning certain guns/equipment for matches (Tournement,custom,public) personally I think you should be allowed to use literally anything available to you without fear of being snubbed by other players with ridicule of some sort! If you don't like getting blew to bits by a claymore in an hardcore SnD match then make sure you check your corners buddy
Oh except target finders.... Nobody thinks that's cool
