it depends if im sucking and cant kill people then i go for the objective so i can blame my low kdr on that but if im miraculously able to kill people i go for kills
i like souls idea of pistols-kinfes-shotguns but only flash/stun/smoke nades otherwise we would just have nades flying everywhere
and make the map shipment
you can only really enforce it if it was only in a small portion because so many people just ignore the chat that an entire knifes only map would be too tedious to maintain
