Hello, I know that these tips will hardly get to where useful, but:

I think we all agree that the two Expert dungeons in 3.4 are fantastic: fast, not boring. Another world than most of the past. At the same time, doing POTD 150-200 I found great fun in the challenge that a dungeon like that could give.

And then: it would be absurd such a separate system in the 4.0? Dungeons xelphatol-like for tomes farming and, separately, Savage or Extreme versions of the same with glamor-based rewards (or pieces just below the tomes gear?)

Maybe with weekly reset. It would also help many groups of players who have difficulty to form a 8 members party, allowing him to make endgame in four.

Nothing else.
