My actual problem with deep dungeons is that they lack half of what make rogue lite systems actual rogue lites: there is no sense of progression once you're max level inside deep dungeons. No loot, no perks to alter or buff your party/job, nothing. This floor system could have been much more with persistent perks that you loot or have to pick from every time you come across one.

There is overall a great lack of things to fiddle with beyond pomanders.
