Oedy, true, even in IL-2 or FB the expert players can and will, shoot ranges over 300 meters. But even so, their concept of "long range shots" is something like a 500 meter kill with a lucky big cannon shot(and a BIG cannon, for that matter - a MK103 or a MK108, or those soviet 45mms... sniping off wings and tails with .50s or 20mms?? Never).
The vast numbers of people ranging from average to decent pilots won't try to shoot over 300 meters, because they know it's most likely waste of ammo. (Since the stability of the planes overall increased in FB, the average distance is 200 meters or so. In IL-2, it was even worse..)
The only real discussion about weaponery in IL-2 or FB is the ability to do critical damage(such as the noted 'bug' instances of MK108s not doing correct damage and stuff..) - almost never about ballistics. Because, the ranges the weapons are fired, like in real life, are relatively close ranges that ballistics don't really show any difference.
Only when the range is unbelievably far, is when ballistics differences begin to matter, which I think, is the case with AH.
You don't hear people whining about Hispanos in FB(well, many people are astounded by its power, but nothing, like in AH 'Hizooka whine'.. ) In AH? I hear "bullshi*!!! You spray dweeb!" venting everyday.
Perhaps some things are extreme in IL2 and FB, but in that sense, so is AH. Though Il2 or FB doesn't necessary have to be a role model for AH, but at least there are somethings which should be noted with keen interest, I think. And AFAIK, they don't do any sort of 'nerfing' in anything.
