The BIGGEST problem for an AH pilot in WW2OL seems to be lack of situational awareness.
No flames please, but lets face facts. In AH you can instantly see when an aircraft comes within I think 6000 yds of your aircraft. You can tell aircraft type, closure rate and from that form a basic estimate of his airspeed and aspect. If he's a fair distance away, you can snap through all your other views and instantly reacquire him. In a fight, unless he goes cold side, you can maintain view on him without difficulty.
It's very different in WW2OL. Distant aircraft initially appear as translucent icons ... you won't know whether it is a friend or foe until he comes much closer. Lose sight of him at a distance, and its gonna take you a few seconds to reacquire. Even when you do, you cannot tell his exact range due to the analog range circle. Consequently, you can never be as sure of his airspeed or closure rate.
In a fierce dogfight, there are lots more places where he can park himself causing you to lose visibility. If he's losing, he can disengage far easier due to this lack of 'instant icons'.
You'll also have to shoot from far closer ranges than perhaps you are accustomed to ... generally its a waste of time in a hard turning fight to shoot unless he is within about what seems to be 100 yds.
It's not better, nor worse than AH: its simply 'different' .... and the differences have been known to play havoc with experienced AH or WB pilots from time to time.
