5 fading door entrance limit. - The 5 fading doors that NCBA had I felt were perfect.
No invisible cameras. - Making this a rule would help a lot in finding bases, especially if they're hidden or if the server is dead.
0 Keypad delay. - Doesn't make that much of a difference, but having a keypad delay while raiding is incredibly annoying.
5 Minute kidnap cooldown. - This seems like a pretty fair cooldown imo. It would encourage playing kidnapper more, as you don't have to wait an eternity to kidnap someone.
