Well, on the other hand, they said something about these dungeons being harder than the lvl 60 ones.
Which is true, because lvl 60 dungeons are faceroll easy, there is absolutely nothing hard about anything in those. The Vault, the Aery, and even the Library are harder than both Fractal and Alwaysreap.

Though solving this by nerfing pre-60 dungeons is not the way to go.
