It's a real shame. I adore things like the original Amdapor Keep and Pharos Sirius. They were technically optional dungeons and pretty tough at the time. Not impossible to overcome by any means but everybody in a group needed to pay attention and not ignore mechanics or slack off in regards to dishing out damage. Both were adjusted...and pretty much every dungeon since has been rather simple.

The Vault was a pleasant exception though even that suffered adjustments to lessen the difficulty.
