I saw a video of players using voice comms in 1.2 beta and it seemed to be working really well. I didn't get a chance to try it tonight, but if it's fixed, in-game, and good for up to 4 players (wing), I wonder if it might be more convenient and easier than team speak. I've never used team speak, so I have no clue about that.
At least for the casual meet and greet, where you run into someone in the same system, the in-game voice comms seems to be the way to go. But I suppose of you are trying to organize several wings, then it's not up to snuff.
Do most players even have mics?
What d'ya think?
