take all that fluff (some of which is pure fantasy nonsense) and toss in prototype/theoretical aircraft as well as actual aircraft with crap flight models and you have fluffed crap...
Speaking about flight models there are two main aspects - the flight dynamics and the flight data
Flight dynamic is modeled very well in WT. The main differences between WT and AH are:
1) Stall warning - it is very short in WT and you need to be very careful dogfighting near the ground
2) Inertia on X axis (elevator) - it is bigger in WT - that makes aiming harder
Everything else is pretty much the same in AH and WT
As for flight data AH was always good at it. To claim that WT is bad first of all you need to take timer and test the planes.
I did not see something wrong so far: for example Ki-43, Hurricane and He-112 turn very well, P-36C, G.50 and C.200 turn good and LaGG-3 turn not good which make sense for me. Plus you must take into account that in WT when you place new type of plane in service you get a second hand one and need to upgrade it to factory standards to get max performance. The additional factor in WT is limited pilot's stamina - if your "pilot" is not trained well he can run out of stamina in intense dogfight pretty quickly and after that the controls become too sluggish and you can not put the plane to it limits for sometime. If it happens in the middle of dogfight and for example you are in Spitfire you are a dead meat to 109 or 190 you fighting with.
To sum up it is still a question what is better to to play with precisely modeled planes in arcade environment (AH main arena) or to play in may be not that accurately modeled planes (it is in question though) but in realistic environment.
The second choice gives you much better immersion of the real fight and quite fresh experience.
