As others have said, I would like to see more Deep Dungeons, but I'd like to see them with a little more variety and action. Take them even further away from the content we get in the rest of the game. Vary up the floor effects and traps. Give us access to more abilities like we can get in Bozja. Randomize bosses even if just amongst a set pool so that it's not always the same every single run. Try to make the content a little more fun to solo on a variety of classes. Etc.
