Champ is unbelievably terrible in average play and from what I can tell he isn't high presence in pro anymore either.
He has a neat role to play as a debuff-based juggernaut but he's too simple about going at his job to a point that the only way to make it fair is to make him really bad early game by nerfing his pillar into the ground.
And don't say it's because there's not many tanks. Nunu and Sejuani have been god tier all season and he doesn't perform as well as you would expect against them, either.
You've done pretty good on Garen, Annie and Aurelion so Id be happy to see another dead champion get revived.
