Someone posted while back, most people are loyal to their country, some of us however are simply rogues who enjoy a fight. As the aces high website says "In the air, on land, and at sea, the battle rages 24 hours a day with participants from around the world."
Some of us simply don't get enough action, we free lance, its already said if you switch countries you can't get the perks for winning a war for few hours.. So whats stopping us from being able to switch?
Make it 6 hours (reasonable), and no war winning perks for 12 hours if you switch... I say this because I generally pop on around 2pm EST to fly on my hour lunch, I switch to find a quick fight, then log back in around 8pm EST, in which i'm bound stuck to a country still that may/may not be fighting again.
If we do, somethings I'd like to see is a countdown clock added to the Clipboard for those who do switch, thus enables us to watch the timer in case we want to switch again, kind of a life countdown timer.
