What about a evelynn W buff?

Make it so if you cast W while insivible if does not break invisivility, and if you hit an ennemy champion while W is active with hatespike, it add extra time to it's duration. IMO that would allow her to be quite more agressive and efficien ganking early, help her hit her E faster (who now might become a event better source of dps as it will prom hit effect, hello blade of the ruined king and trinity force)...it would still not solve all of her problem (jungle substain)..but would help her become a better ganker and assasin.
