Being the simple man I am, simple solutions appeal to me. Breaking down the current dilemma here and trying to reduce it to it's base common denominators I've defined the root elements of multiple simple equations:
A = disparity
B = skill
C = planeset
D = challenge
E = fun
F = success
The only variables seem to be perspective. Let's see if we can arrive at some common ground. Let's presume a majority consensus within perspective groups for simplicity sake (knowing well that anomolies may exist on each side):
Axis group claims the definition of the Allied group is A = B
Allied group claims the definition of the AVA setup is A = C
Allied group claims that current C increases D and decreases E
Axis group claims current C increases D and E
Axis claims B = F without A + C a factor
Axis group claims Allied B = (- Axis D) while also claiming their choice in C is to create more D for themselves due to an overabundance of Axis B and a disparity of Allied B.
However, a B deficit on either side has a direct relation to the other side's D causing a D deficit (if common sense is to factor in).
If Axis C = Axis D = Axis E then (Allied - B) = (- Axis D) = (- Axis E) to a degree (any of which the Axis group should be glad to diminish if not eliminate).
Even with disagreement on the previous formula there should be somewhat of an agreement on the final line. It being the focus of an arrived solution.
If fun = challenge and the Allies aren't providing one ... *AND* ... if Axis pilots F = B while Allied pilots - F = - B ... then why don't the Axis pilots train the Allied pilots? No ... not just fight them from the cockpit of an Axis plane in the AVA (not unless the Axis group really *doesn't* want a challenge). Let's see the top three Axis hotdogs take planes of the Allied groups choosing while surrendering their preferred rides to Allied student opponents and go to the DA and make films complete with audio for training purposes.
This kills two birds with one stone. It firmly establishes pilot skill superiority *and* helps rookie Allied pilots over the learning curve hump so the fun challenge for the Axis pilots can increase and they won't get bored suddenly when the planeset goes latewar and the Allies have the Spit V or Hellcat or ... whatever.
And ... to make it fair (and even more interesting ... the top three Allied hotdogs can embarrass themselves by returning the favor.
Call it ... the AVA hotdog challenge. Or ... if you will .... "Top Gun School" (the best pilots always fly opposing force, right?)
Dis-cuss.
