How about just doing two dungeons, with no divisions? I think most of the active posters on the forums are either already skilled players or at least aspire to be.

One comment I wanted to make re: purist, especially since I think I'm the only one who posted a score with the purist medal on this latest dungeon (

) is that it seems pretty likely that non-purist strategies would have had the decisive advantage if there were more participants, or participants had more time/energy/kingdom gold to devote to the challenge. I literally cannot think of a way to improve on my Rogue or Priest strategies' medal count (everything but Hoarder and Faithless for the Rogue, sans Parched as well for the Priest), since the dropped medals were all essential. (Doesn't mean it would be impossible to come up with a better strategy, of course, but I'd like to think it's unlikely.) Darvin and gjaustin's non-purist strategies, on the other hand, most likely could have taken the lead with slightly more optimal play and/or luck, since they both had opportunities to pick up more (or more valuable) medals.
What that means for scoring is beyond me, though, aside from the need for more data. And I somehow doubt we'll see many purist medals in a vicious contest, especially with class constraints...
