The operative word here is "co-op". I had given thought to an idea that required the players to join a mission in order to fly. No more lone wolf runs. This would reinforce the idea of formed squadrons.
For the most part the misconception has been that players know what they want and they want freedom to do what they please. Well, good luck with that. Or I should say, that sounds like anarchy. So, instead of being able to have many different types of fights. The options are actually more limited.
Another problem with the current mission system is that they are usually not very many variations of it. Very rarely do folks make a mission to fighter sweep or to strategically attack enemy resources. Mostly mission planner use is to either form the NOE raid, bomber run or base take horde.
Something along the lines of enabling AI to fill in small formation missions, would give the "fun" historic planner types a chance to grab less popular aircraft, and not have to scrub the mission for lack of participants.
Co-op might not be the term I was looking for, and Chilli, one of the ways I was looking at it would be a separate, dedicated missions arena.
They would be pre-loaded auto launched snapshots so to speak.
This would give everyone, including day time players a chance to fly in large missions.
One drawback would be that there would surely be low number times when most of the slots would be filled with AI, but you would never know for sure what type of pilot you might run into.
Again, since the biggest gripe would be having to dogfight against AI, it's a good thing that fighter escort and interceptor slots are more likely to be filled first by players, maximizing the chance that you would be dogfighting other players instead of AI. I don't think having bomber formations manned by AI would generate the same level of disappointment. Of course bomber jocks could also replace AI bombers if they wanted to participate as well.
Also might be nice if you could spawn into a mission and replace an AI plane already in flight, if a slot was available, so you would have a choice as to whether to join a mission in progress or wait for the next one to start.
