Obviously, I've only been at this a day, but I've found the social aspect to be lacking. Besides queuing up for The Devil's Lair or the Crucible, I have been running solo. Not because I want to, but because grouping, seems to be non-existent. It would be nice to be able to announce, either in the Tower or when I land, "Hey, I'm about to do this quest at this difficulty, who else wants to group up and run it?" I could go thru roster and send a message/invite to everyone in the area, but that is not very efficient. For those of us who don't friend everyone they come across, this seems to be just an all online solo campaign. But that is just me.
