Barbs are the most effective class in the game in terms of dishing wide spread damage while being on the move (most effecient farmer). Wizards are next, Monk probably 3rd. Theoretically a DH is supposed to have absurd damage with some specs but the gear required is too much. Like a DH can basically one shot a pack with a well placed Cluster Bomb or Loaded with Bear if it crits.
So...Witchdoctors are utter garbage endgame then? Not even worth putting on the list?
Not asking sarcastically, I'm genuinely curious. I loved the class when I played Diablo on PC release but damn was it a struggle later with the crappy mana regen speed.
