I would complain that Engineers repairing critical damage to tanks and structures simply by burning them with welding torches and Pak-40's being wheeled around by two men ruined my immersion but this is just a video game so I suspend my disbelief and have fun with it. To each their own.
when i played with plastic toy soldiers as a 9 year old kid I didn't faction mix, its not fun its boring, it simply makes the subject matter of the game irrelevant, just because its a video game doesn't mean you should crap all over the contents of it in my opinion, the Allied - Axis side of the game I think is the most fun thing about it, you can use your imagination with all the stuff you mentioned, faction mixing sort of eliminates your ability to do that.
.. maybe the player base may have been bigger with at least a tick box, my whole clan might have only been 20 players, but faction mixing lost the whole clan in a vote because we came from the game Blitzkrieg and all of them loved the history.
