Game mode : Play against your friend

Would it be great to be matched against your friend not in custom games ?

1. You enter the queue as a team of 2,4,6,8 or 10 friends.
2. You are matched with other groups of friends (of same strength, like normal or ranked queue)
3. The line-ups are shuffled and some of your friends are on the opposing side (half of it)
4. Blind or draft picks
