So a friend of mine wanted to RAF with me, but is not able to do so cause she lives in the US (she's from europe thus the european account)
What exactly is the point of this? Why are you not allowed to use the RAF service in the US on a European account?
Was the response from customer service.Thanks for contacting us in regard of your issue with the Recruit a Friend promotion not available for your World of Warcraft account.
First of all please accept my apologies for not being able to get in touch with directly in game.
In regard of your issue I regret to confirm you that while United States laws are absolutely not against the Recruit a Friend (they have their own promotion!), you are not able to send a Recruit a Friend invitation from an European account.
They give you absolutely no information other than it's not allowed.
