Damn...This would be an awesome concept for an Ultimate skin.
A "Yin-Yang" concept I'd say.
Her Q goes in as white (absorbing the other person's good) and come back as black (true damage to a person that has only evil). Her W are like fired up charms. Her E would be like a Yin-Yang looking gas-projectile. Her R would leave white-black streaks. AWESOME!!!!!!!
