If your 5 levels higher then the mob, you get no exp, gold or loot (except crafting materials like leather)
This also means no Undaunted exp in private\instanced group dungeon but you can get some from the quests in there.
If you bypass all the private\instanced group dungeon until higher levels, its very hard to level Undaunted
