In the expansion I would love to see dungeons coming back as an experience for groups of 1 to 5.
Now we have pve contents for groups of 5 and 10 but no endgame content for smaller groups and solo players so dungeon could cover that.
Dungeons don't need to have a big story arc connected like the original ones, that might be too much work. A vibe it's easier, like the fire dungeon where you obviously(like cof) you get to fight fire enemies and a quest giver asking you to get resources from the dungeon.
Dungeons could be reworked to be an endless dungeon delve, with modular rooms with encounters, jumping puzzles and puzzles that randomly spawn and the deeper you get the more resources and loot you get.
Dungeons could be finite with a definite map but with a chest at the end that replenishes every day or like 3 times a day that gives you good loot like stuff for the ascended equipment or legendary so there is more push to actually run it. They should scale depending on the party size and could have at least 2 leveles of difficulty, the hard mode being for hardcore players and giving more loot. So you could go for hard mode and run less dungeons or go for easy and run it more times.
I know it's not a new idea but I'm really missing this kind of content and I think it could be possible.
What do you think?
