So OP have you even gave balance a shot at 50? Or is it not your play style without even attempting to try it, its quite enjoyable, you can kite people easily and there is burst if you know what your doing, its my favorite shadow spec, but also I don't play infil because I have a scrapper scoundrel and I don't play KC because I have an ironfist vanguard, but balance is imo the best spec for a shadow
