Dungeon+ system?

[Shurrikhan]

and this is why we don't have +type dungeons lol

all their efforts go towards new stuff instead of minorly adjusting old stuff.

"Minorly adjusting old stuff" isn't what's being requested here, though. The cost of a dungeon+ system is almost entirely frontloaded: you build the system to thereafter affect any dungeon automatically. Only when balancing around non-granular reward efficiencies is much of any precise tuning required. With the one system, you can increase the time which one may spend, with due reward, in any dungeon tenfold or better.
