I think my system of real WWII scenarios would be better.
Take Eastern Front air battles, for example...
You have two sides: Germany, and the Soviet Union. There's a rolling planeset, and the planes you can fly depend upon the year the battle took place.
I know that the Combat Theater does this... But seriously, it would completely balance the MA, and would also promote serious flying (not just for perks and score).
But for now, Patch 8 is a good way to balance the MA.
