Here is how to fix kog without reverting his rework.

So the entire premise of current kog is pew pew very fast. so fast that you cant move or kite.

So how about this. turn his W into a channel that roots him to the ground. this will turn him into a literal artillery turret. since its a channel, each shot should cost a small bit of mana aswell so that he can be further limited.

like he should not be able to move AT ALL while his W is active because lets face it, 5.0 atk speed is straight up broken. there needs to be restraints on that in the form of debuffs. i dont get why riot is so scared of it. they did it with blitz W so they can do it with something thousands of times mor broken.

so to reiterate,make his W a channel and make it literally root him to the ground. while he is channeling each of his shots cost mana. maybe increase the range slightly aswell.

the main problem with the kog rework is that it was a pure buff to old kog in every way possible. massive buff to W, buff to his R, buff to his Q. only thing that remained exactly the same was his passive and i think his E.
