The thing is, you’re also competing against more well-rounded aircraft who’s weapons are for the most part, superior to yours while having only a few setbacks.
a fight at 4000m where everyone will be in the 300-400kmh range is different than a fight where you’re going 500kmh, the guy you’re gunning for is 400 feet in the air and he’s slower than you.
Similarly, you can still be in danger in an advantageous position. I mean, look at Ki-44s or A6Ms. I can run forever, but trying to engage them is nightmarish when I know they can at least critically damage me, if they hit anywhere, while I’ll need to strike directly into their fuselage for anything appreciable.
If I have to be hyper specific where my guns hit, and no one else does. Why is that fair? I’m not even talking ‘realism.’ if everyone is broken why can’t my guns be?
Similarly, most of U.S. belts consist of AP anyway. If U.S. incendiary got a buff to at least push the fragments out a little further instead of literally glitching inside itself and suffering the realshatter bug like the other guns did before the fix like with the images I posted of U.S. incendiary. Why would that be a bad thing?
