yeah let me tell you there are SO MANY dogfights going on these days (read: none. like at all.)
You are very naive. The point isn't that there aren't dog fights, the point is that if put up against any of these planes save for all of the ones I posted (b52, V22, AC130) it would have its titanium alloy ass handed to itself.
That, and the way things are going, it'll all be drones and high-speed jets. The A-10 WAS good for Iraq, afghan and the like, but now we're at least TRYING to leave. After that, the A-10 will just go down as the bathtub that was capable of flying.
Oh, and of they continuously fire their cannon and eat up EVERY bullet, it would stop in mid-air.
