In StarCraft II league play, 2013 Season 3 has begun! Bonus pools and standings have been reset, and 2013 Season 2 milestones have been awarded. You can take a look at your 2013 Season 2 results by visiting the Leagues and Ladders section of your character profile.
Furthermore, Season 3 brings a host of new maps to the 1v1 and 2v2 ladder map pool. Take just a moment to get familiar with all of the new maps by checking them out here before you hit that "Find Match" button in the game.
As always, the hidden skill ratings used for matchmaking and league placement carry over from one season to the next, so if you were already placed in a league prior to the 2013 Season 2 lock, you'll only need to play one placement match to kick off the new season.
Good luck, and have fun!
