Urgot rework suggestion

So hey all. I thought I might come up with some ideas about Urgot Rework Suggestion since he's on the free week and he's.... well. He's been falling apart here and there.

His Q and E are his bread and butter. The only thing I would apply on this is "Q can critically strike and apply on-hit effects." Reducing opponent's damage with his passive seem good enough so I won't be touching that.

His W and R, I believe, we could change it to something like this. "W - Reinforced Ion Thrusters: Urgot moves a certain distance with his thrusters, boosting his armor and MR for 3 seconds. While Reinforced Ion Thrusters are active, Urgot slows the enemies by 80% with Acid Hunter by 1 second, but he's slowed by 50% as a result of his additional bulk. Activating it early will allow Urgot to gain a 20% movement speed buff. " "R - Siege Mode: Cataclysmic Projectile: Urgot roots himself and arms a slow-moving projectile that homes into the target, channeling for 2 seconds. Projectile may be intercepted and opponents can see who is the target, though not which direction it is coming from, and increased gains armor penetration. His E range is greatly increased along with his Q for 10 seconds while rooted, though activating the ult early will cancel his siege mode early and allow him to get a 20% movement speed buff."

R at max rank will have Xerath's Rite of the Ancients range.

Thoughts.
