It’s a great idea in theory but in reality it would be a nightmare. You know those squeakers no-one wants in their fireteam? They’ll be in your ear 24/7 in public areas and those people that want to share their love of thrash metal and rap by playing it over their mic...24/7! Yes you could mute them but legit players would get sick of muting offenders and would eventually leave the channel altogether so the majority of the people you could talk to would be the people you really don’t want to talk to! Also, in my experience the only time players use proximity communication is to troll or tell people how bad they are. If somehow the gaming community matured and used proximity communication to actually help each other it would be a great addition to the game. Imagine how much easier things like EP, Gambit or Blind Well would be if we could communicate with randoms, it might even reduce the edge stacked teams have over solo players. I just don’t think it would ever be used to it’s full potential and would instead be abused by trolls too much.
