When you guys play Super Mario and see Goomba coming do you stand still or jump?
Come on, it's Diablo, like one of the main chars in the game, I really don't miss that pussy of a Lord of Terror we've had for years. His two deadly strikes are easy to dodge even as melee. Only problem can be that fire nova that doesn't really give a warning, maybe removal of knockback is enough for low-hp builds to survive.
On hell you don't even have to bother with him until lvl 125 and if he causes trouble then... it's time to give up.
