Blizzard today revealed a new feature coming "soon" for the Dungeon Finder. Once this service -- as they're calling it -- goes live, players will be able to party with Real ID friends cross-realm and run dungeons. This will be available to any of your friends on characters that are the same faction as yours.
Slorkuz goes on to point out that this will be part of a premium service, meaning you'll need to pay an additional fee to use this Real ID grouping feature. However, only the person inviting will need to pay the fee.
The details on the additional cost, and release date, are currently unknown. But Slorkuz does state that we may begin seeing elements of this service appear on the PTR.
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 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.
