Daily reminder Vayne has a 34% play rate and a 53% win rate.

Your reasons are not even valid. But sure, I'll elaborate.

Average games played is a measure of the average games played on that champion someone has. Meaning, when you see a Vayne queue up, that person has played, on average, about 95 games. Leading to a 52.86% win rate. To compare, when you see a MF queue up, that person has played, on average, 53 games. Leading to a 51.06% win rate.

I'm sorry, but if you don't think that playing over 40 more games on a champion should allow you to have a 1.8% higher winrate on that champion, you're not very smart. I mean, you're literally saying that experience on a champion shouldn't matter. Do you realize how dumb that sounds?

Your "counterpoint" was that it means enemies have seen the champion more. No, it simply doesn't. For an exaggerated example, a champion could have an average games played stat of 100. But, if only 10 people are playing that champion, that means the champion has only been played in 1,000 games. So only 5,000 people have played against her (not counting duplicates). Compared to if a champion has an average games played of 10, but if 100,000 people play them, the champ would have a total of 1 million games played. Meaning 5 million people have played against that champion (again, no duplicates). The stat you're thinking of is playrate.

The problem isn't that Vayne is "too strong". The problem is that people like you bitch and moan that early game champions like Draven and Lucian are "ermehgerd oppressive" so they are nerfed. Then late game champs like Vayne have an extremely easy time in lane and can reach carry status much sooner. Then you'll bitch about Vayne being "cancerous" and "reaches her power spike too soon" so they are nerfed. Then you'll bitch about early game champs "not paying a high enough price" for being strong early, because they "don't fall off late" now that you've nerfed the late game champs. You say Vayne is cancerous because she spikes too soon. Well maybe that's because the community has bitched and moaned about early game champs being "oppressive". The champs that dominated Vayne's weak ass laning phase and kept her from getting items and spiking soon.

And Vayne's playrate is so high because she is relatively easy for how strong she currently is. People can say she is difficult all they want, but the only thing difficult about her is positioning, which is pretty universal for ADCs. She can be played perfectly fine with just playing AAs. There are no combos. There are no skill shots. So when you nerf the champs that keep her in check early, stopping the early spike, you get a lot of people playing her.

But she doesn't even have the highest win rate for ADCs, despite people that play her having the absolute highest experience with her.

But no. Just continue to look at win rate only and judge a champ's power. These things should go without being said. They should be common sense.
