Isn't the Ta-152 considered a 'high altitude' fighter though? It was designed to excell at high altitude. Historically many dogfights occured up high as opposed to what I've seen in AH which takes place mostly under 10k. What doesn't work so well for us may have worked well historically.
It has some characteristics that make it very dodgy. In reality, it was rushed through production, before some of the development prototypes were halfway done (or something of that degree) with their assigned trials. Many, probably nearly all of the pre-production models were put into service before the end of the dev cycle too. The development feedback from evaluation in active squadrons and official evaluation crews was between a mix of brilliance and some worrying flaws (and some overall praising comments such as one top pilot calling it his life insurance in the last days of the war), and really damning comments from the Rechlin evaluation officials. One of these actualy said something to the effect that one particular flaw could only be fixed, as far as he said, by modifications that were unacceptable (reducing fuel tank mass). This specificaly matches our plane.
There were also some issues of stability (again like ours), though they can't really be seen in-game as described in the literature because we have perfectly still air.
All in all, it was a very promising design that was nearly stillborn because of Germany's state of attrition. I can't recall where I saw it, but at some point it even says one development crew or other that worked on the plane had to get their drinking water from the firefighting supplies. A batch of planes waiting to be delivered were strafed on the factory (IIRC) airfield.
Landing it isn't difficult; only there's a pretty thin line of no return, since it's pretty heavy (lots of momentum) in unfavorable spots (the tail) and the gear is pretty flimsy.
