This suggestion is based on the current push by ZoS toward hybrid-focused gameplay with the intention to promote build diversity.
The suggestion is that the vampire and werewolf skill lines get a slight rework along those same lines. Alter morphs to be one side magicka, the other stamina. Vampires could choose between skills that promote caster type skill OR melee martial artist type attacks. Werewolves could continue along the lines they are now or choose morphs that make them more shaman-like in skill use.
