I would argue that because the Spitfire can do everything well the pilot learns much more advanced ACM.
I disagree.
In a spit16, you can follow many different tactics and still win. Yes midway, its extremely forgiving.
Look, im a noob, as we all know. Still, about a year ago, when i learned some tricks (tailwhip, hammerhead etc), the spit pilots were just wondering what i was doing. I improved since then, but still dont know anything.
Most of the spit pilots just do flat circles and think they own while the plane is working instead of them.
They dont need rudder, nor flaps, nor throttle management, just pull the stick back and you win.
If you wanna learn ACM, fly a ki84, 109F, whatever. You can get the same results, but you MUST be "working", also "thinking" to be effective. They help you to learn how to use your whole plane.
Then, if you hop back to the spit, do the same moves, using all your control surfaces, you will feel like an unbeatable god.
