Hunters, while far from worthless, do seem to be slightly less useful in VoG. It isn't their fault, it's just how the abilities interact with the VoG's mechanics. Take arc blade for example. In PvE, it can get you killed easily unless you're up against a horde of weaker enemies. In the VoG, this only happens during the templar fight. But using it then makes it easy to accidentally become marked by a fanatic.
