I think its unrealistic to be able to hear the guy behind you shooting... Is it possible that this could be incorporated to the game? I mean if I was behind someone and fired with no tracers, he shouldn't hear me coming should he?
I know this has been a feature for some time, but possibly with the new version we could do away with someone in a WWII type aircraft hearing another aircraft coming as he/she has one or more engines running.
And I guess the same would go for turning your engine off to hear GV's (IL-2 and such). Just seems "gamely" to me. No one in there right mind would shut down to go GV hunting...
