Win Rates Mean More then you think
Win rates are a used metric but I continually see people use win rate as an excuse to justify nerfs/buffs on champions that often don't need them. There is a lot to a complex game like LOL and I just wanted to point out a couple things you can tell from win rates.
These are the top 5 win rate champions.
These are the bottom 5 win rate champion.
What do these champions tell us? Is Anivia too strong? Does Leblanc need buffs? We can't tell from this information alone. What we can tell is that champions with high win rates as well as low win rates have similarities.
are all champions with simplistic easy to understand kits that have identifiable weaknesses and strength. They have forgiving abilities that are a big part of their kit and require little skill to use. They are easy to play the first time you play them (compared to others). They do not have walls of text built into their kit that requires a lot of knowledge to understand how to maximize their power. In essence, they are easy to learn champions that people can pick up and be effective with really quick.
we can tell from this champion selection that the champions that end up with low win rates tend to have complex kits that require a LOT of skill to use. A lot of text for many abilities making for complex understanding how to maximize their kit. Nidalee in particular has 7 abilities and not just 4. Azir is one of the most complex champions ever made in lol. Ryze has walls of text that require some pretty deep understanding of how to utilize his kit properly.
What I see with win rates is a message that complex champion naturally have lower win rates. This makes sense because all the new players that pick them up are going to need to play a lot more games with these champions before they understand their power and know when they can win fights or when they need to play safe.
I also see that simplistic champions have higher winrates because it is so easy to be effective with them. You can understand their powerspikes and moments of strength in just a few games if not the first game. This makes a lot of sense when you think about it because you will figure out the champion so fast and not lose as many games once you understand them.
What else can we tell with this information? Well we need to take into account that simple champions with low winrate are likely weak. Rek'Sai is the 10th lowest winrate champion. She is surrounded by complex champions but her kit is very easy. This raises warning signs for me that Rek'Sai is in need of some buffs when such a simple champion has such a low win rate. I understand that she has a global ult but Shen, TF, Galio and GP all have a higher win rate. Taking the win rates in comparison with other champions gives me far more information about what a champion needs. There are obviously other factors to take into account but I have more information about Rek'Sai and her needs by taking win rates as a whole and not just her win rate alone.
What about the flip side? The first complex champion I see with a high win rate is Yasuo at 51.76%. That is pretty close to 50% and win rates fluctuate all the time by 2-6%. This doesn't really raise any flags but if his win rate was consistently higher like around 55% that would be cause for concern because he has a lot of complex mobility in his kit as well as many other features that need to be learned like 3rd hit Q, how to get reliable knock-ups and windwall placement.
There are also outliers that can tell us something is out of wack. Sejuani's recent 60+% win rate was such an event. This was an insane amount of win rate for any champion and it turned out that her passive stayed active when under a shield. That was op as enemies couldn't even break the shield making her practically immortal. Anything over 60% is something that needs a look at.
There are a lot of things we can tell from win rates but just saying X has Y win rate doesn't tell us anything. Take it in context of win rates in a whole look at the champion's win rate and compare that champions kit to others and see if something is out of wack. Don't just grab a win rate and try to beat people over the head with that stat. Use some deductive reasoning as to why that win rate is good or bad. There will never be a time where every champion has 50% win rate. I doubt we will ever have a time where all champions fall in a 48-52% win rate range. That is just the nature of the game.
