Dynamic Groups will kill ranked.

"DYNAMIC GROUPS

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.

Ranked teams will still be available for players who want to form a team of any skill level, as teams are judged on the skill of the static group rather than the sum total of the individuals. That said, this season we're also going to be improving the path to pro, with less ranked team grinding and more focus on performing when it counts. Details to come! "

This is a horrible decision for those that play solo queue. This would completely dump on proper matchmaking and MMR. Why would I queue solo when in high likelyhood the enemy will be premades on skype? Isnt that the entire point of separating solo and team ranked? So we dont end up with horribly one sided games? Throwing a faceless 95% chance this wont happen isnt gonna cut it for the times it does.
