The Group Finder lists Durnholde as having a minimum level of 64, but you can’t actually attune for the instance until 66, when you get the quests.
Its not just Durnholde. Its literally every dungeon in the game.
We are unable to queue with friends who are only 2 levels higher or lower than you. Even though the dungeon’s say we can. We are unable to queue up.
They haven’t fixed this issue in over 6 months. They literally don’t care about our dungeon farming, because they just want us to buy boosts. Its so sad and disheartening.
