I think it would have to do with something about giving clear and simple objective at hand to the people who fly.
In the days of the war, winning the war was the first and largest objective, but also as a living being, using one's military forces to fight a fight where your soldiers survive, and the other side's don't , was an absolute necessity. Smack-down, head-to-head, frontal-collision type of game of attrition was a costly move which even the sure winners would hesitate to play.
In actual tactical combat, it seems there were also other type of objectives at hand which kept the pilots struggling to survive and yet, chained to combat. Surviving was necessary and yet, you can't just grab alt alone, ignoring all your squad mates in the dumps. You can't just run away screaming leaving others to get shot down and die. In other words, no matter how good a pilot is he was bound to his mates by duty. If one chooses to run and leave all his friends, being the only person to survive everytime, he'd probably face the military court. People were given a mission as a group, and aborting it was an option to be chosen only when there was no other option.
So, I guess real life was a mix of factors of "survival" and "forced duty" which, in the MA, there is nothing that has to do with both. No lives are stake so no need for flying to survive, and no forced duties so one can ignore everything and everyone if he chooses to do so. Thus, the only objective in the MA that is remotely worth something is winning the war. People couldn't care less about flying smart, or carrying bombs in a flaming kamikaze. Nor do they care about group tactics or have concerns about the safety of their team mates. I guess we can't really expect that in the MA, and that's why probably mission theater is in plans.
All I can hope for is a some sort of a management system which judges the pilots of the new Mission Theater which accounts for more factors than required in MA - "survival" "forced duty" "cooperation".. etc.
Accomplished the mission, but failed to survie - low points
Survived, but abandoned the mission - low points
Accomplised mission and survived, but all your squad died - low points
Acomplisged mission, survived, and lot of squaddies also alive - high points
