I don't think thats fine. The thing flies like a lawnmower. If you push a lawnmower off a cliff and hit an enemy plane with it, that doesnt mean that the lawnmower is a great dogfighter.
Even the German officials in WW2 stated that this version was way too undermotorized and more or less fixed the problem asap by the introduction of emergency power system (basically just some simple modifications that allowed more air into the engine and higher pressure).
When you are ED and want to develop a nice new plane, why would you take the worst version that ever existed of an iconic fighter plane? The Dora and Kurfürst are later 44 models as well and Anton was modified in June 44. Imo it's just sad things are like they are - I would have loved to have a nice Anton in the game.
