RIP yoloQ 2015
This upcoming season we're replacing the solo/duo queue with a dynamic group queue, where you'll be able to climb the ladder with any number of teammates, going from single participation all the way to a full team comp. There's no longer a penalty for players ranking together, so the benefits of grouping up will always prevail. You'll still need to be of similar rank to your queue-buddies, and the system is designed so that groups will almost always play against similarly grouped opponents (so if you're in a premade five, there's a 95% chance you'll run into another premade five), but now you'll be able to compete the way you want to.
