Blizzard has announced limited region linking is coming for StarCraft 2. The change will allow players to connect with a larger group of people and is a welcome change within the SC2 community. The regions Blizzard are linking together are the European and Russian communities, the North American and Latin American communities, and the Korean and Taiwanese communities. In short, the linking process will allow for more multiplayer matchmaking options including finding faster ladder and custom games and finding more precise opponents at or near your skill level. You'll also be able to create Real ID friendships with people in your region.
Once the linking process is complete, all of the players from the linked regions will be combined into one ladder. Players matchmaking ranking will be unaffected by the change. Blizzard has also said that linking won't impact players in-game latency or game performance either.
Adding region linking to SC2 is a good first step for global cross-realm play. Probably the most interesting piece of news to come out of the announcement is the linking of the Taiwan and Korean servers. As of right now you need a Korean SSN to play on the Korean StarCraft 2 servers, but you don't need one for Taiwan. Meaning if competitors want the absolute best practice they can now purchase a Taiwanese version of StarCraft 2 to play with the Korean players which they previously didn't have access to.
