Just a thought here.. An arena that is like the dueling arena, except that say every 5 mins, flights are started at 10k. You sign up like a mission 5 p51's vs 5 109's. When they are full or after 5 mins it starts. Something like Call of Duty is what I had in mind. This gives you a quick team, no climbing, equal numbers and no worries about more planes coming in to pick you from a nearby base.
Now before this is torn apart, it's just a thought. Somtimes I only have time to fly for 20 mins or so. This is a Gamey idea, yet this is still a game. And yes this could be organized in the dueling arena already, but that would be tough. ok... have at it..
