Now in Retail, joining on Squad tries to join you into their game. A second, third, fourth, and so on attempt will continue to join you to their game. We're no longer able to join their squad and chat to see how much longer their game is or anything worthy of communicating.
I feel led to believe that since their's a separate "join game" option, that "join squad" should at least allow you to join a squad of a group of friends who are currently in game and chat with them, until their game is over, at which point you'll be able to join them "in game".
Could I get a better understanding of the intent behind "Join Squad" and "Join Game"?
