S!
Osprey, english is not my first language so some posts can sound harsh. What I meant with working with planes is that I bet most people here have only been in a Cessna or an airliner, seen planes in an airshow etc. Very few actually fly planes or maintain and work with the inner parts of a plane or with their weapons systems, depot level repairs and maintenance etc. When you do that and are in contact daily with real fighter jocks the flaws and limitations of a simulator/game become more and more obvious. So there it is: Game.
Spitfire was a great plane but IMO a bit over glorified. It did not win the BoB or WW2 alone, Hurricane did the grunt of the work in BoB for example. In other theatres it fared like any other fighter, but it suffered from same as Bf109: short range. It had it's vices too

Sissyfire came from the idiotically modelled 25lbs Mk.IX which everyone and their aunt/granny/uncle flew and touted it being historical. The Spitfire is still a graceful sight, but for me the Bf109 has a sweet spot always.
Osprey, you contradict yourself a bit. You say the Sissyfire will be the "world of pain" for blue. Is that the only plane that will be checked by Luthier? Flying blue is a challenge and with the comment "world of pain" you just confirmed it

How about later when the Fw190A's whack the Sissyfire Mk.Vb silly? The tables turn later with Mk.IX to more even etc. The circle goes on and on. So there is no "world of pain", just adaptation to the changing situation

And when you learn to fly blue against the reds flying red is a breeze. Agree?
So after all..this is a game we enjoy to play. That's it. Sure creates heated debates but still we play. And tactics work in this game in most situations as the features(FM/DM/CEM etc.) of the game make it possible.
Well, over with this. I think all just want a game that is as accurate as possible within the constraints of our hardware and software.
