I use the in-game voice-comms ALOT. My game is not an individual one. Personally, I dont see any problem with the way the channels are setup now. You have the "Local" channel if you want to get all "realistic" and only talk to those near you, and you have the "Team" channel if you're like me and enjoy getting the whole team on the same page. I think if you hinder the communication for the sake of realism, like most of the things I read here in the suggestions page, you risk taking alot of the fun out of the game. Theres a delicate balance between gameplay and utter realism, which is something I think the devs have done a great job on, with what they had to work with in the Mod version. Do we want realism? Of course, but without controlling every minute (mine-oot) aspect, to the point of reducing your gaming experience.
