I also noted voice chat doesn't always work even with friends which mean't we had to reset machines, log back in, re group and then launch to the destination again. But yes not many people talk, even when they get joined up in to your fire team as part of the Strike missions but then it's up to other people if they want to be sociable. However I certainly don't want to listen to a bunch of screaming, singing, swearing, racist, homophobic degenerates that seem to populate gaming from time to time and drive me mad searching for the mute button!
