I don't know but from what I seen from the forums the lack of communication between strangers is one helluva deterrent in this game.
In and out for the Tower I seen one of the most gripes was about the lack of a means to communicate with strangers and ease of grouping.
As of Beta it was a major hassle.
How do you all feel?
