With AH's view system what difference does it make where the ammo counters are? Just map key pad 8 (forward view) so you can take a quick snapshot of the counters. Or get trackIR... I can't understand why one would need to stare at them constantly, to count every bullet? A quick look to see how much ammo is left should be good enough.
I play allot of FB/AEP/PF and folks get along fine without ammo counters (and icons, damage list and a lot of other stuff described as 'crutch').
However, my aversion to the ammo counters is that they are hideously ugly. If folks in AH must have exact ammo count (I do agree what Kweassa stated, ammo counters do dictate the conditions of the fight more so then even fuel) then put them in the E6B.
It seems that they have some talent for making cockpits in AH2 (AH1 stuff was always horrible). I hope one day they bite the bullet and go for more historical cockpits. However, I don't think AHs player base would tolerate that.
