Have you ever wanted to run a dungeon with friends who are on different servers? It looks like you'll soon have that option, as long as you're Real ID friends and of the same faction. Here are the details from Community Manager Nethaera:

"With the continued popularity of the Dungeon Finder, many players have been asking for a way to group up with real-life friends who play on other realms to take on instances together. Today, we wanted to give you a heads up about a new feature currently in development that will allow players to invite Real ID friends (http://us.battle.net/en/realid/) of the same faction to a party regardless of the realm they play on, and then queue up for a 5-player regular or Heroic dungeon.

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."

Yes, the post does state that the feature will cost money. What do you think? Would you pay for this service? You can discuss the topic in this thread in our World of Warcraft general forum.
