new darkin

i thought about a new Darkin. i was thinking, we have a sword, a bow, we even have a scythe, and one thing we don't have in all of this is that we have no defense. we have only weapons, and could use with some defense, so introducing the Darkin shield, the most basic of defense. but what i was thinking was , Aatrox has complete control over his host, so does Varus, and Rahst and Kayn have a love hate relationship, so how about this, new champion has a co-operative relationship with his Darkin shield? perhaps the more kills he gets the less doment the shield goes because its clear he doesn't need the Darkin, but the more assist he has the more defensive he becomes? and if your fully in control of the Darkin and its gone fully passive then you get to throw the shield, but if the shields in control then you take no damage from the next attack. like a perfect contrast, like they balance each other out. like yin and yang. maybe the person who wields the shield is like a monk, or a pacifist. i know this sound just like Braun, but i want him to be more interesting and more cool and to have like this dark side to him to make you fall for both of the characters and show how they contrast and have perfect synergy. some sort of black and white to them.
