Microsoft own Blizzard. Microsoft have every intention of putting Blizzard’s catalog of games on their xbox pass for pc. They have all but said this is going to happen, but when is anyone’s guess right now. It makes zero sense for microsoft to continue down this subscription path limiting people being able to play or wanting to play. By having this game on the xbox pass is opens it to millions of players who would otherwise probably never play wow, and it’s not as if they [players] are giving money to Blizzard either.
What does this mean for migration? It makes perfect financial sense to close Blizzard EU because they won’t even be needed when this game ends up on the xbox pass. I suspect all accounts in Europe will end up on american realms. It saves Microsoft a ton of money. The sooner the better imo because it will open the game up to far more players, which this game desperately needs!
