You're arguing the "realism" of which icons are displayed on your WW2 digital E6b GPS radar MFD?
Im not defending the rest of it either. But there is a tolerance level/threshold etc. Eventually you add enough crap together and its pushes things too far and makes certain things too hard to do. Additionally, not all unrealistic mechanic affect BFM and tactics. Some of them just make certain things easier, without altering combat. Or they might alter combat so little they can be compensated for without having to bend over backwards.
And yes, I will argue realism in general. This is a flight sim. If realisim was completely meaningless then this wouldn't be the game that it is, and hi tech wouldn't need to even attempt to make flight models etc.
I do not understand the certain members in this community who have been playing a game for over a decade who seem to want to turn this game into war thunder. If you want that, go play war thunder. Its the perfect unrealistic airquake game. You all start from two fields, engage in a climb off to altitude, and no one can ever run froim you because you have map edges and icons that reach out to 20 or 30k so long as someone on your team can see that enemy.
