1. Have all the gunner positions in buffs available for anyone who wants to jump in.
2. Have minefields near vehicle spawns, that way you can spawn a GV without dying to a camper, warn a camper that he is approaching a minefield, if he keeps coming then he dies, that way the rest of us can actually up a GV.
3. Have icons switched off in the Allies v Axis and snpashot arenas.
