I think the auto-mission is really an interesting idea, although I myself never use it, simply because I have a certain tactical style, and don't trust the computer to use it. Still, I think it's a very innovative idea that addresses the developments in the genre, and there's no reason to take it out. Rather, it will facilitate the play of those who tire of the ground missions, and should remain in the game if it's not a burden to the developers. Developers, well-done!
