I tried queueing for the slave pens and i can't. When I try to queue through and Earthen Ring Elder I get the queue screen in the dungeon finder for a fraction of a second and then it queues me to other dungeons. This is more than frustrating at this point so I hope someone will help me deal with it.
I'm afraid that you are unable to queue for this holiday event using the Dungeon Finder because you are not yet a high enough level. You are welcome to participate in the event by forming a group manually; however, the Dungeon Finder will not present you with the option to queue for the event until you have reached at least level 78.
