If you replace it with superstition you will never run out of fury with that build. If you have no idea what you're talking about you better shut up and don't make a fool of yourself.
Mine die pretty fast with that rune. Can you link your profile please?Together as One is really the rune you should be using if you have 4p IK. Not only is it Lightning damage, it makes you pretty indestructable. I went from slowly clearing t2-3 to dropping war cry / defensive passives and being able to solo t6, albeit slowly. Even at lower torments, Together as One lets you drop all defensive passives which definitely makes up for any rage issues (which in my experience, there is none anyways).
