Keep in mind that once Global Play is released, you'll be able to switch regions on the login screen and will NOT have to download multiple StarCraft II clients.
But we all know that CN service will not available to join the Global Play. So I have a question:
If I want to play in CN service, I will not only have to buy a CN account, but also download the CN client or use some 3rd party tools to change my US client into CN client. Right?
