What I was thinking of doing was creating a target list we have to bomb say on the Rhine map. For each mission both the attackers, and defenders will be graded on target destroyed %, against losses doing it.
That would give it more purpose than just a mission.
When we run the tenth mission, an overall tally would be made on the effectiveness of the campaign.
I know what you are saying though, thats why there are so few in the AvA. It just takes a little imagination in the AvA and a few willing people.
