If there are any changes to the dungeons, it may be to pets. They don't seem to have any damage resistance to the 5000 and etc Needles and can pretty much be instantaneously killed when people won't stay off of them, even if you place them. :p
Now that people are getting the hang of the dungeons I think they're seeing that they're not hard, it was just new mechanics that didn't "click" yet.
