Officially nervous. I want to be able to play single player content and not have other people around. Because often, I just want to soak up the world or go about a very specific plan I might have, and not have anyone else involved.
Obviously I don't know what that means, just seeing other people in the game, or how it will affect what I do. But conceptually, I would like to see a wall between my single player sessions and when I want to go and be with other people. This sounds like they're working to remove those walls.
