[2023] Why is no one talking about how Rammus has a 43% winrate?

https://lolalytics.com/lol/rammus/build/

Despite being a simple, non-pro play champion, he has the lowest winrate in the game, lower than Yuumi, Aphelios, Zeri, Corki, Kalista, etc.

I searched the subreddit and no one has made a post about it. Am I missing something? It's not like people are going with an old build either. Every single max order has a low winrate and every tank mythic except Radiant Virtue (which only has a 19 game sample size so idk if the 73% winrate is usable)

All data taken from lolalytics but OP.GG also has a 43% winrate and U.GG has a 41%.

I know the winrate will go up when all of the nom-mains drop him, but it is still such an absurdly low winrate for a champion that shouldn't be as hard to play as other typical low winrate champions.
