Yes, I agree. I did not venture in DH yet so I cannot say. From what I understand people just run through mobs without fight?. Also what could add difficulty is a random factor for bosses. Either be a random boss at the end or that the boss has 2 phases and the 2nd phase is random between 2-4 different outcomes. So yeah, again after a while once you know all the different outcomes and how to fight them it gets easy, but at least it's random so you still got to pay attention.
