Add Between Clearence and Omni a Special Keycard that opens Your teams Door of spawn, For instance MTF gets Armory keycard same for SD so they only ones can acces and open doors to their spawn making it impossible for Campers to get in, Same for CI if they get changed From just a Giant spawn hole to an Actull Spawn with door that only they can acces it.
I see no need for an armory card + campers can’t really stay inside your spawn considering you have a forcefield when you spawn and could easily kill you, having to resort to the hallway where again, if you make it out of your spawn in time you would still have a forcefield
