They're more or less stated in yesterday's live letter that the MSQ dungeons are going to be hard as they usually are (AKA not very), but then later claimed the level cap dungeons would be harder.

After ShB and EW's "expert" dungeons...I'll believe it when I see it. Amaurot and the Dead Ends somehow ended up more difficult then the optional level cap dungeons that followed them, which isn't a very high bar, but still...
