How to nerf Kench from a Kench main

I've been playing Kench since release and he is by far my most played champion. I have around 150k mastery on him. There's a lot of talk about how bull shit he is and I agree. He can be extremely oppressive to melee champs iand his team fighting is obnoxious to play against.

My opinion is the stacks on his passive need to be looked at, and increased to 4 or maybe 5 from 3. I don't think the damage he does is unreasonable, considering he doesn't have the same team lock down cc other tanks have like Sejuani, Amumu, etc, but what was supposed to gate Kench from just immediately devouring opponents is really hardly a restriction at all. If you are a melee like Renekton and try to trade with Kench, it's aa - q - aa and you are eating within seconds. You get so many kills as Kench from doing this and spitting the opponent either to your own turret or your jungler.

In team fights this also applies. You can try to kite him but Kench only needs to be on top of somebody for a moment and boom he's fcked. Devour should only work if the enemy is actively all inning and trying to kill you.

You can't really play around it. Raising the stacks would greatly raise the window of actually trading with Kench and make him feel a lot less oppressive.
