And this justifies perking it on what grounds?
See the NPA concept. Links in my sig.
It doesn't justify the perking of
only the La-7. However, it does justify the perking of the
entire section of fighters that are in the 'La-7 class'.
The MA, especially since the changes in gunnery, is now undeniably shifted towards a virtual environment resembling late '44~ '45. It's a time where most of the basic aircraft tactics and performance levels have been already established, with multi-purpose fighters.
The planes of this era is very powerful in performance, is usually able to carry out multiple tasks, and also generally very high in survivability.
It renders all the other planes in the planeset between 1940~43 utterly useless, or at least vastly incompetent. Not to mention takes away the role of most jabos and bombers in the game, and shifts the game into a sterile, bland environment where only a handful of superplanes are used again and again.
