I think this is something they are missing, dungeon events that offer good unique but are harder, for example maybe bosses have timed attacks and you have to work as a team either you get one shotted, this is something lost ark did offer and challenging, this would be based on your level so you wouldn't be put with someone level 100.
Lost ark has daily like chaos dungeons but also bosses that get harder on each level, the problem with D4 that there is not really much to do apart from Dungeons or Helltide. you do sometime get events in the world but they are very few and far between.
I am surprised that they didn't add either a knight / paladin character but then blizzard does not like fun.
Is it me or does the game feel lifeless?
