I just recently found out about that you actually have to discover the entrance of an dungeon in order to queue for it, or get in it through random dungeon.
Now, I've got a group together planning on farming dungeons, like reeeeallly much. What I would like to know is that is it enough if one player in the group has discovered the entrances, or does every group member have to discover an dungeon so that we can queue for it?
Hiya! I wasn't on the beta but based on hearsay I'd say with 80~% certainty that every member needs to visit the entrance/dungeon itself in order to be eligible. Much like the equipment requirements for the heroics I'd guess you would get a similar message saying one of the members doesn't qualify if you attempt to queue otherwise.
