Voltaic spec is garbage and people will learn quickly they can gain utility and damage with a hybrid tank / madness spec.
Look into and get back to me before you laugh like a noob thinking there is one and only spec.
Given the cool downs on the operative it's simple to macro the rotation. Try doing that with a real sin spec and not lol voltaic slash shock. The kiddies will like that because its simple but hardly best or highest damaging.
