In the upcoming content patch, a new dungeon system will be added that will take the place of the current Looking For Group system. This will offer great new benefits to both premade and randomly created groups, including:

* Cross-Realm Instances/Grouping
* Instance Teleporting
* Daily Random Dungeons
* Group Disenchanting

And much more. Learn more on our new dungeon system preview page.
