one of the lines in this video by Strider Gaming is giving me an idea that
kill/death ratio should be hidden for the entirety of the round, and should only be displayed when the round ends
a reason for this is that in the original, a number of people would try to be lonewolves and just sprint around the map trying to kill as many people as they can (not actually helping the team) just to feel good about themselves after seeing the kills when they're dead
a removal of kill/death scoreboard when the round is being played would put even more emphasis of teamwork, instead of solely kills and such (a number of players just run around to get kills and not helping the team).
I hope the devs will consider adding this suggestion as a native feature in the next Insurgency
