You can now create your own ranked games with a friend! Create game --> create game --> uncheck unobservable --> uncheck unranked. Sometimes it doesn't work the first time and you have to check/uncheck unobservable couple of times. Congratulations! You now get to play ranked with your friends, what could possibly go wrong?
