Teemo players also have on average about three times as much experience as Hecarim players in both of Hec's common roles, and doesn't have nearly as high of a win rate when comparing people with 125+ games (which a fifth of all Teemo players are).
I mean, I never found Hecarim particularly OP (but then I can't recall the last time I saw that guy and I wasn't the one playing him), but comparing just the win rates does nothing to prove your point.
Swain...

Can we have the playrate as well please? You forgot about that one ;)
