The Dungeon looks great (as all of them), even again with a small story, which is nice I think. Cool idea with that new difficulty! I did not really test around, just made every level once and am now about to do the lower class restriction runs, so I cannot discuss the gunner one or an class-open one yet. If insanity is the new madness and madness is a bit easier than in previous dungeons, this can help many (newer) players a lot I think!
Again it is a missed chance to implement event soul frags as rewards for every run (only gunner Krampus and Ferryman had this so far!), but gunner frags are also needed and as far as I understood, only one Minotaur is exclusive for the event soul, right? So I guess we can live with that.

Happy grinding everyone!

@URock: I also had this message - potato server had a hiccup again, but after a few minutes I could continue, even without restarting the app.
