Idea for Urgot Rework

OK so this is going to be one of my "Just for fun" rework ideas. I like to imagine how I would personally remake a champion. I love current Urgot and don't find too much wrong with him, but if I was given the choice to rework him, I would try to emphasize the painful shoddily done cyborg aspect of him.

Visually I would change it so that urgot has no legs whatsoever, and instead has a giant painful looking cybernetic claw and arm that he uses to drag himself along the ground, with his other arm being completely replaced by a bolted on artillery launcher. Also I would change his Auto Attacks to be a melee attack where he slices his giant claw hand at the enemy, but have the AA range of a ranged attack.

Passive - Acid Hunter: All of Urgot's abilities apply a small true damage DOT for a short time, the DOT going under the name of "Noxian Corrosive Fluid" (like one or two seconds) (for brevity I will refer to noxian corrosive fluid as acid). Along with this, once every second, a homing blade (scales with AD) will shoot out of Urgot for every enemy effected by acid. (in other words, anyone effected by acid will be targeted and it can simultaneously fire at every enemy within range)

Q - Mass Execution: Passive - Whenever Urgot kills something, they explode in a small AOE with physical damage based off of your AD.

W - Terror Capacitor: Shield yourself for a small amount, this amount is increased for every enemy effected by acid when the shield is cast.

E - Noxian Corrosive Charge: Shoot a canister of acid out of your claw, it lands and sprinkles enemies with acid in an AOE, along with dealing bonus physical damage based off of your AD.

R - Hyper-Kinetic Position Anchor: Urgot is rooted for a brief moment as he channels winding his arm back, then in a split second reaches out in the direction of your cursor dealing heavy physical damage scaling with AD, knocking aside any minion and will suppress the first champion struck for a few seconds, constantly refreshing acid on them, and heavily increasing the attack rate of your acid hunter. Hitting an enemy champion with this ability also automatically casts W, even if it's on cooldown.
