I see this topic has already been discussed in the Beta forums, but since I didn’t participate in the Beta, I’ll just repeat my request here.
My wife and I would like to join our friends in playing story missions. However, we’ve got responsibilities and our free time to play in the evening starts at varying times. When we get on to play, most of our friends are already in the middle of story missions. With missions being between 40-60 minutes, that means the possibility of syncing up with our friends in the time we have to play, at best, 2 story missions is nearly impossible. It’d be nice if we could drop into a game our friends are hosting that is already in progress, or that they could join us in our game.
Of course, we work around it and are ok to drop out of our game to join friends, but it sure would be nice if that wasn’t necessary.
