Dota 2 Matchmaking Update - Ranked Fee Under Consideration

The Dota 2 Blog offers details on a ranked matchmaking update for the new season for Valve's MOBA. This covers a lot of territory, including Role Symmetry, a Draft Role Report, a connection of Core and Support Ranks, new player ban waves, thoughts on smurf accounts, and more. They have an interesting thought on possibly adding an access fee to ranked play to help combat smurfing (creating a new account and stomping newbs). Here's that:
Smurfs: Dota 2 being a free-to-play game introduces various matchmaking related challenges. One option we have thought about is having Ranked access have a one time entry cost, and that access can be lost for players who regularly ruin games. We may also grandfather in users that we have enough data on, but we haven’t gone too deep in assessing the details here. We aren’t sure if we need this as a solution yet either, we hope that other solutions can have a good effect at improving the matchmaking ecosystem.
