As this is a fairly complex service to develop, we don’t have a release date to share quite yet. It’s important to note that as with some of the other convenience- and connectivity-oriented features we offer, certain elements of the cross-realm Real ID party system will be premium-based, though only the player sending the invitations will need to have access to the premium service. We'll have more details to share with you as development progresses -- in the meantime, you may begin to see elements of the feature appear on the World of Warcraft PTR.
So with this, do you think we could eventually see cross realm arena teams with real ID friends? Would you support the idea of being able to arena with a real ID friend on another server? I know it would save a lot of people in the AJ community who transfer to different servers often to play with new teams, quite a bit of money
