Short of restricting kits i’m against anything that forces people to play a certain way.
I favour encouraging people to not play conquest if they are going to camp, by a sniper game-mode i suggested here: Sniping game mode
Encouraging the hide and hunt players AKA campers to play a mode tailored just for them would get them away from conquest while still leaving the regular conquest mode open to more active snipers that try to help out more.
