As of now dungeons are segregated into sections and players are forced to complete the same objectives just to progress. Free prisoners, etc.
I would rather they not focus so much on giving players more tasks. The game is absolutely loaded with mundane activities because of this philosophy.
Nightmare dungeons should be simple and to the point. Long dungeons with a single objective, optional events that reward glyph experience and random modifiers that are not chosen by the player. This adds a ton of variety to the content.
Now instead of optimizing and catering the entire experience for ourselves and drooling from one area to the next players can simply “explore.” It’s a profound thought.
