For me, the staged missions are about historical immersion and best suited for a venue that doesn't have the any plane from any country dynamic.
No doubt the same for most scenario types.
But just like many other aspects of this game, three country set-up or free choice of aircraft for example, concessions are made to appeal to a wider demographic and keep the MA highly populated.
If done right, there could be enough formations in the MA that you could quickly organize a scenario (attackers and defenders) with specified aircraft in a "cold" part of the map.
It wouldn't be an exact historical scenario, but it could be enough to create sustainable interest in those types of activities in the MA between regular events.
I suppose that in an MA type setting, AI bombers might be more palatable than AI fighters and provide a gathering point for fighter combat.
Absolutely no AI fighters.
What I want to do with them wouldn't really fit in the MA,
It could all go in the MA, they just need to bring the game out of the last millennium.
