Currently, it only exists in a Fireteam, but why not the world? If I'm in Hellmouth, and there are 5 other people in the region, I want to be able to talk to them. To join a Fireteam is a tedious process, it kicks me out of my current Patrol, just to make me load from orbit 20ft away. Or in Crucible, either nobody else turns on their mic, or there is just no way to talk to your team..? Is this to reduce the strain on the PS and XBox networks? I really can't understand it. I feel like I just bought an MMO with millions of subscribers, just to be antisocial :(
