I'm not sure what new arenas of gameplay HTC has in mind, but one thing for sure, is that there will never, ever be a "Relaxed Realism" arena in AH.
Now, I won't comment on your personal preferences, as not everybody shares the same definition of 'fun' when they enjoy AH. but I have to say that you are really missing out very much when you limit yourself to relaxed realism.
Dealing with the intimate but difficult learning curve, is time consuming and can be sometimes frustrating, but the reward is like no other, and the excitement of competition and combat beats the stale stimulation of an air-combat sim gone the way of the 'point-and-click' FPS games.
I can say it so, as I've also enjoyed a lot of Relaxed Realism air-combat games of various kinds, especially played Fighter Ace for a long time. For some time I've considered myself to be an excellent virtual pilot, until I've ran across AH and learned that I sucked, and sucked bad.
Had to learn everything new, and each time gritting my teeth and thinking "ooh, if this stupid game hadn't so much stalls and black outs and red outs and limitations in ammo and fuel, I'd shoot them all down". But then again, there were always people who manage to shoot others down with those same limitations. If they can learn to do it, why not I?
And that, started a long enjoyable time with AH.
I'm sure if you gave the more realistic surroundings a real chance, you will learn to enjoy it more as I have. Cheers!
