also dunegeons have been a staple of offline rpgs, and of course dungeon crawlers since they were created, i dont know why going online means we shouldnt have levels designed with monsters a setting, a theme, and a boss in there as a main means of entertainment, when it was one of the more entertaining things about rpgs.

I also think they should make dunegons not so linear, in that there should be secret special stuff discover, maybe some story elements, or hidden bosses/areas etc.

they should also add more content to overworld things, including NMs you pop and whatnot, big super monsters that everyone can join into fight /open missions.

other things, for replayability quests/missions with time rewards, performance judgements, survival elements.
