Janna's win rate? (Why win rate is a limited information stat) Also buff Karma!

Yep, still 54%ish even after mini-rework + many many nerfs that followed (including big hit on her shield). Win rate by itself is a terrible stat for determining how good a champion is unless its ridiculous like 57+%. The small 45-55% win rate spread is pretty much based on how easy a champion is to use and be effective with. I will grant that Janna is easy to play because her abilities are all decent reward and very minimal risk. Ease of use being tied to a high win rate is a direct cause of auto-fill especially in support role as people get auto-filled to that role the most. It's no surprise that the highest win rate support champions are those that can get by just by placing shields on allies because you have players filling that role that often do not play that role. It can often boil down to "you just don't feed" when in an auto-filed role. Being able to play passive should always be an option but that option allows passive champions to exist and by nature a passive champion will be able to sit back and play...well...passively. we also have to allow a 5% give or take from 50% win rate (45-55) because its just not every going to be possible to reach 50% win rate on all champions.

There are two things win rate can tell us.

1. If a champion complex or simple.

2. If something is way off balance.

That's all the data we can get with win rate alone. Even if you throw in play rate that doesn't change the fact that it is just a larger pool of people getting the win rate. Win rate is pretty limited but we can use it in ways that does show there is a problem. As we have established that simple champions tend to have higher win rates and complex champions have lower win rates we can take a look at Karma.

I think it is safe to say karma's kit is pretty simple. The only complex choice comes from deciding which ability to use her R with. She has a basic AoE skill shot, a point and click tether, and a point and click shield. However she has a sub 50% win rate in both support and mid. I would feel safe in saying that Karma needs some buffs as other simple champions like Sona, Janna, Soraka all have much higher win rates. Also more complex champions like Rakan, Braum and Bard have higher win rates as well. By using win rates of other similar champions in the role and comparing kits we can get an idea of a base line idea of what to expect from Karma.

A simple long range poke shielding support should have a much higher win rate (currently 46.46%) but does not. I would also point out that her shield is the strongest with her R compared to all other enchanters and applies in an AoE for ardent this is another red flag that Karma is woefully under performing as currently strong items that favor her kit do not bring her win rate above other non-ardent supports like Leona, Tahm Kench, and Brand.

The point of this is that win rate is a statistic but you can't just say "X champion is too powerful because WIN RATE". Compare the win rate to other win rates of similar champions in that role and then present the data as evidence and not at fact. It's a far more convincing argument. Also, I think we should buff Karma.

Lastly, The only time you should give only win rate as an example of something off is if the win rate is WAY off the mark of 50%. Currently Ryze mid sits at 42.49% win rate and that to me is a big flag something is off for him. I know he s complex but maybe too complex when landing spell rotation? I would say it is fair to say something is off if a win rate is higher then 57% or lower then 43%.
