Bench the Kench !!

So i know that often times when people complain that a champion is (OP) it is due to players not making the correct decisions in lane or poor mechanics make opponents seem op, However i believe Tham Kench is one of the most broken champions in the game due to the fact that he is a early game bully that evolves into a late game menace with insane tank stats yet still has the dmg to 1v1 anyone because of % health W. His abilities have short cooldowns yet still chuck you. If you try to fight him early you will lose and if you don't stop him from farming he becomes practically un-killable but still does insane damage because he builds straight health and resistances and does %health dmg that scales off his HP. I think he is a good champion and has a really good kit but playing against him is ridiculous! A few things that I think can be done to better balance him would be to add a extra stack needed to proc his passive and reduce the hit boxes on his Q and W because as it stands if you exist the Q is going to hit you, it has a lot of range and a wide hitbox, and the W has a weird range. He autos with his tongue and if his W is a bite it should at max be the same range as his autos, but he just magically gains range to eat someone. Also when he spits a minion at you the splash dmg that applies his passive is way to big. It hits you if you're anywhere near it! you can be behind the minion wave and to the side of the ability and it still hits you. Over all i think these proposed changes will make it harder for him to just bully his opponent but still keep the strong dueling potential for the people who continually try to fight him. My goal is to increase the window that champions have trade against him so that dominance in lane in'st so absolute. Giving people the chance to farm and shut him down before he gets his tank items and is no longer killable. If you agree please up vote this thread if you disagree please tell me why.
