I´m sorry but that´s an oversimplification, and in any case combat aircraft are made to either shoot something down, bomb something, and transport something. And most of us are mainly interested on the first two roles, otherwise we would be flying a boeing 737 on a civilian simulator.
There is none two bombing missions equal, and none two aerial combat equal, each engagement is diferent, and that´s what make it interesting to do it all over again, specially when you are getting more and more real physics modeled.
Also there is a lot of varitey of targets and combat areas that make everything diferent.
If you are tired of flying missions where you have to bomb something os shoot something, then why bother to buy and fly a combat flight sim?
I´m not against the idea of having maybe rescue mission, or flying a transport aircraft to a pocket zone and drop cargo to the troops while there artillery explosion all around, and come back, but they should be rare exception because you will get tired of them way more quickly than flying combat missions.
Anyway, its just an opinion.
