Or, in the case of Silence, very broad and not enough to flesh out a class with.
And unlike Demon Hunters, which have a very solid theme to work around, despite other classes having their abilities, Dark Rangers do not. It would essentially just be a petless Survival Hunter with more shadow damage. Really, even moving out to a more broad-scope, the ranger class overlaps too heavily with Hunters.
Furthermore, lorewise, Dark Rangers are Forsaken only. There's no real "lore bending" that would result in both a still-respectable story, and the Dark Ranger class opening up to other races.
