What? No, they do not need to be harder than Rabanastre or Shinryu, nor should they start off at that level either. I swear, there is no middle ground with you. It's either this or that, never something in between. Bardams Mettle, at that point in the story, reinforces what you should already know. Maybe in later expert dungeons, you can have them at a few steps below the kind of difficulty you would face with Hashmal. I hear what you're saying quite clearly - but you keep going straight to "it must be at near Savage level" to be effective. No, it does not if Expert Dungeons start increasing difficulty. Nor do you need to have hour long dungeons. These suggestions aren't for vets that raid... This is something for casual to midcore as a buffer to the sudden difficulty spike in Savage, or really, something for other players not interested in raiding, but looking for something relatively challenging. Not everything difficult has to go straight to punishingly difficult. Just because you personally won't do it doesn't mean that there aren't other players who won't.
