I would like to see a 15 min down time if your KILLED in a fighter, GV or bomber.
Say your up in a Fighter and you get KILLED, you would have to wait 15 min's before you can up another Fighter. I think People would be a little more cautious and I wouldn't have to kill the same guy over and over. I think that the true art of dogfighting, tanking and bombing would really start to show in the game.
