It was only meant to be more mobile than core guard. Which it is. 1200(1500) range on longbow and area denial with traps gives DH a kit that does not need insane mobility. It already has multiple gapclosers and F2, thats enough. In a world where thieves(i am speed) getting mobility nerfs, DH does not need a mobilty buffs. Playing DH without some type of movement speed rune is a terrible experience
