Some of the real crackshots may not notice the difference in AH2. But I don't have a stellar hit accuracy - about 6~8% average in the AH1 MA. And personally I feel AH2 gunnery is indeed harder than AH1. I see a lot of situations where I mistakenly fall inside 400~500 yards from a Spitfire, and still escape without being damaged. Were it AH1, it'd be highly probable that I'd have been shot down at those ranges.
One of the reasons is the tracer is less visible, making it harder to 'walk' the rounds to the enemy over 500 yards.
Also, the hit sprites are very hard to see over 500 yards - not many people are tempted to 'spray' with confidence, knowing that they're gonna hit the enemy, when you don't get a return info on whether you're succeeding or not.
Just those two changes made it enough to make some people feel AH2 gunnery is harder. If we get rid of the ammo counters, I think it'd be pretty complete.

Even in AH1, I don't think 800yard shots are common. What makes it a grueling experience is the only planes which are capable of putting in those long range shots, are those with multiple .50s or Hispanos. Other guns rarely ever get even lucky hits, over 500 yards.
IMO, it's not the 800yard shots that people should be sick of. I think it's pretty rare a thing to happen.
But rather, it's the average ranges where AH gamers confidently feel that they can get a kill, that should be brought up as a problem.
You're chasing a bogey that is extending away from you slowly. He's at 400 yards. If he jinks hard, he's gonna be caught. So, he jinks and maneuvers lightly, trying to get away from you.
Now, how many AH pilots can't shoot him down? I'm an average pilot. But I can shoot him down. If I have .50s or Hispanos, then I can most certainly shoot him down.
