There is nothing quite as terrifying as hearing a distant persons voice off in the dark unknown while exploring Chernarus. The only problem though is that everybody, including my friends and I, are using outside VOIP programs to get around the in game direct communication feature. Thus making communication possible without ever giving away our presence. My suggestion is that the in game direct communication is ALWAYS on so any sound coming from your microphone gets pumped in to the game. Maybe this could be hardcore server only thing or a toggle feature set up by the host.
