You can easily combine the DF style with the coop style with the mission menu, which is claimed to be working after the latest patch.
That existed already over 6 months ago. You just need to find enough player interested into that kind of gameplay.
And there lies the problem.
There are servers which already use the mission menu call up of missions on dogfight servers. Methinks "king1hw" is trying that concept with introducing a "new server" in the online section.
Unfortunatly I cannot spent my time into further developement of this at the moment, due limited sparetime and other priorities.
And frankly spoken, the game is not in the state yet in which you could fly coop-style online wars anyhow. The network issues are too dominant to use significant AI online, the crashes are too regularly experienced by a too many players to motivate squads to dedicate their time. It is simply too frustrating to organize a squad of 12 pilots bring them in formation, just to see that the half of the group, has to quit because of CTDs midflight.
