I remember the discussions of MA strat some time ago. Karnak and Wotan stated "attrition has to be left out as a factor".
Maybe its time to reconsider attrition factors.
How about a concept of "stores"?
A field will be given x amount of fuels, ordnances and fighters, bombers and vehicles. It would just be set to infinite when no field strats/hangars are damaged.
However, once a fuel tank(for example) is destroyed, and it shows 75%, this would initiate the attrition factor on the field, with the x amount equivalent to the 75%. Each time fighters or bombers, vehicles up from the field the fuel amount would be used up. When additional fuel tanks are destroyed and gets down to 50%, if there was fuel stores over 50% prior to destruction, the stores will be reduced to 50%(which would be 2/3rd of the x amount).
Same with the hangars. Once a single hangar type is down, the infinite stores for that plane type will be changed to limited stores of x amount.
This would make a lot of people think twice before just wasting away their planes in a suicidal jabo onslaught - both for the defenders and the attackers.
The problem with current "percentage-based strats" is that it has virtually no effect unless its down to 25%, which limits most of the planes. Take down 25% of fuels on an enemy field and still infinite planes can up with 75% fuel and go pork another base.

Having more people on the side really SHOULD mean heavier burdens in logistics and resupplies, maintenance. In typical MA situations where the Rooks are the underdogs, if a massive air power decides to attack a Rook base, having limited fuel and sorts will naturally effect the side which has more numbers more seriously, than a side which is lower in numbers.
This would also help revitalize the necessity of resupplying bases in literal terms, than current resupplies which is really nothing but speeding up the rebuild process.
There is still much to think about, but I think sooner or later, the factor of attrition and logistics must kick in.
* More numbers SHOULD mean heavier burdens in logistics and resupplies.
* More numbers also SHOULD mean more people have to actively take part in resupplying bases.
