lol yeah, guess you would have to limit how much information was displayed. I guess you could also limit who has control of strategy by taking command like the current CV situation.
All of the information for the person in command of strategy could be set by going to the HQ building - could even have additional information on the progress of the war there, percentage of people flying where , percentage in air, what the enemy (known enemy using radar bars/dots) are doing etc.
Would make rank mean a bit more, and possibly add another aspect to the game.
With the flight plans, it would be for each person only so only they would see it, only people who you invite to join the flight would then see it also.
