Yoshi made it clear we won't see anything unique about dungeons. After the original Amdapor Keep and Pharos Sirius dungeons were a snooze fest. It's kinda shame really it's like anything that requires thought or mixes up the norm is shunned upon. What they should do is make all these instance dungeons actual open world areas at the same time and have unique themes to them, while also having the instance form working the way they are now.

I think that would be a pretty cool feature and would make the open world a bit more lively.
