I don't want dungeons that are hard because your gear suck, that's what the old dungeons are for. I want dungeons that are hard because boss mechanics and hard trash encounters. A dungeon should not date itself because gear progression. In my opinion that's an example of a poorly thought out instance.

Take City of Qarn for example, the bees would instantly one shot someone if they were not killed in time or their final sting not stunned. You could not ignore the mechanics of the 1st boss because they would wipe you.
