I personally like it realistic as possible, but that's not going to fit everyone. Just shed some realism settings - although I might agree that perhaps more fine-grained options for realism might be appreciated for some people.
I'm guessing, for instance, that you're not very interested in DCS A-10C. There literally aren't enough keys on a keyboard for all of it (MAYBE with all the ctrl/alt options), and you constantly have to use the mouse to operate systems in-flight... you also have to manually turn them all on, wait for them to bootstrap, etc etc. That's what makes it brilliant, and that's what I want out of CoD.
That's fine if you don't like it - you can turn down the settings, but please don't assume that's the way CoD should be for everyone
P.S. if you really think you don't need separate mixture/prop pitch/radiator controls, you haven't flown a damaged Blenheim back to base
