Bungie has stated that the team has plans to add Voice Communication to Destiny before the end of this year. Destiny is really limited in terms of communications in all the public activities. This is a short term solution, and one that Bungie hopes promotes team activities.
Our vision for Destiny is that all players, even matchmade players in the Crucible, Strikes, the Tower or public spaces, be able to communicate with one another in a way that promotes positive socialization. Voice communication is the easy answer, but existing voice paradigms, including those in our own Halo games, have not done enough to protect players from abusive griefing from a minority of players.
Destiny’s near-term solution will be to allow players to opt-in to voice communication during matchmade activities. Work on this feature was underway at launch and should be rolled out this year in Strikes and the Crucible.
