I'll preface this with the fact that I do agree with you on these points. I think a lot of Devs do as well which is why more recent games like MW and BFV have massively trimmed down on these features. I honestly don't really remember, I didn't get into shooters before then. I'm not talking about voice comms, but the actual SS headsets you could sound-***** with certainly weren't common until <10 years ago, at least not in my experience. Surprised it made it into CS even briefly, though. Doesn't really fit that game at all. Though on one hand game mechanics get you some information for "free", on the other the limitations of those same mechanics cause you to miss out on a lot of information you would otherwise obtain naturally.
