One of our huge maps on the right hand side has a finger of water that runs south past a V base. Then it has a hidden canal that circles the map. When you fly off the map over that canal, your weapons fire, bombs drop, but do nothing. CV's get hidden there for the duration of the map and tolerated with the general knowledge of the fact. Some argument can be made for the heat of the moment and you were forced there in a fight during air operations. Kind of lame since you know for a very long time where that boarder is.
If you cross that line, your bullets, bombs and rockets should no longer work when you cross back into the active game arena. It's like teachers today saying kids will be kids while watching your kids cheat on a test using their cell phones. Suddenly cheating becomes a noble enterprise with no consequences other to those who refuse to be cheaters in that school. Either going off the map is not wrong and get rid of the arrows calling it super NOE stealth mode. Or some boundaries have to exist to not insult your paying customers who play by the few rules in the arena.
