Are guest passes region locked to the same region as the game you purchased?
If I buy a US version of D3, can a friend use EU Battle.net with my guest pass?
I know that guest passes don't have Global Play, but that's not exactly what I'm asking about.
Solution 1:
Yes, they can use it. I have a friend in China that is currently using my guest pass from a U.S. retail copy of the game.
