For this reason, we’ve decided to make Grandmaster League available only for the latest StarCraft II expansion level. In this way, it will always be very clear who the top 200 StarCraft II players are in each region, and the league will maintain its significance as we move through future ladder seasons.
This change will go into effect for the North America, Europe, Korea, and Southeast Asia Battle.net regions once 2013 Ladder Season 4 begins at 12:00 a.m. on Monday, June 10 in each region. It’s important to note that this will not be immediately reflected on the Grandmaster League section of the Battle.net website, though we will be updating it soon.
Thank you, and good luck to everyone in Season 4!
