Last night they took down the NA servers before I got a chance to play to log in. So I changed my region to EU and was able to login and begin the HOTS campaign just to get the starting feel and to see what the campaign achievements are.
When I switch my region back to US will my campaign data still be there or will I need to start over?
Best Answer
Campaign, Achievement, Account Profile Name, Ladder Rankings, and Save Game data are all stored regionally.
Every time you change to a new region, you will be starting from scratch (though you may be able to move local copies of your save games manually).
