Cant you just open them again? People can just queue, right? And premium members can have their priority pass actually mean something. And i dont dig with this 'external players' thing. What have you got in mind, ban non EU players from the EU servers? That wouldnt be cool. Sometimes people have friends in other parts of the world, and you want to team up with them. Ya feel me?
Sorry man. I do not currently have an estimated time when they'll be back up, but I promise to keep you posted.
