The Dungeon Finder comes with a few other things that players need to be aware of. Mentoring will not work in Dungeon Finder groups. Also, groups that finish a queued group together can have the group leader choose to queue for another dungeon afterwards and loot options are set and locked to Need Before Greed by default for Dungeon Finder groups. Players using third-party interfaces may also experience some issues and need to use the default UI.
