AW not AH2 though... it's one of those things, it'd either work awesome, or work as good as early war... who knows, you could very well see many people jump all over it. Just looking at late war stats, you can see that many of the most popular rides are the fastest. Why not go even faster?
I wouldn't mind seeing a Korean War arena. In fact, iirc, it was mentioned as a posibility when the arena split came along.
and yes, the F-86 is freakin' awesome. Radar gunsight would help alot with the brief firing solutions... and if you're in the MiG, well, you have cannons, higher ceiling, better climb, better acceleration, etc.
If any arena could truly epitomize the evolution of gunfighters, this would be the one.
I keep my account open, but very, very rarely play. This would definately get me back in the chair for several hours a night for a few months.
