Personally, i think the gunnery is about as good as it should be.
It still makes you work for that kill, its not exactly hitting a barn door with a banjo, but at the same time its not so unforgiving to make air combat in AH less rewarding.
I understand there are many hard core flyers out there that want a real chalange and want EVERYTHING to be %100 acurate.
But as with any bussness, you need to cater for the masses, not just the elite few. AH is a steap learning curve as it is, we loose alot of flyers in there first 2 week trial, but if you start making the whole ablility of getting kills harder than ever, we would have even more fresh blood leave after 2 weeks and maybe quite a few of the exsisting ones who are not so HOT with their aiming.
I concider myself to be fairly good, but if i found i wansent hitting anything it would really spoilt the game for me.(prob would never happen cos im an ACE

)
As will all online games, the balance has to be between what is realistic and what works for the masses.
Some may well want a more REALISTING gunnary, but is it going to be practicle.?
