The difficulty of Niobe Labs definitely looks nuts, like a mini-Raid or Dungeon in its own right up to 11. But the Last Wish took nearly a full 24 for just a single team to beat (under-levelled, but still), that changed the Dreaming City for everyone, and it was not long until it became a relative walk in the park once everyone knew what to do. That's Niobe Labs - the real difficult part is figuring out the puzzles. But once those are done and the way to complete them is fully found out, Niobe's Torment should be doable for everyone.
