I have an idea to stop a bit of the foolishness with folks switching sides and "hiding" the CV.
Simply don't allow anyone to command a CV group unless they have been "in country" 12 hours. Use the same timer as the side-switching limit, only now make it so you can't command a cv or switch sides again for 12 hours. That should solve some of the dweebery with high ranking players switching sides and sailing CV groups out of the action.
Alternately, let 'em command, but just make their rank 0 for that 12 hours so that anybody already in country out ranks them until their time is up, then business as normal.
