Overall Win Rate vs. Win Rate By Games Played
I brought this up in a recent game and was a little shocked to learn that everyone besides me judges champion balance based on the overall win rate rather than looking at players who have taken the time to master the champion, which I believe gives a much healthier look at how a champion is doing in the long run.
This mainly stemmed from a discussion about my current distaste for Kha'zix destroying in the Jungle. Although his win rate is only above 50% overall, at 200+ games played it's over 58%. High skillcap, yes, but perhaps slightly overtuned.
Which do you use to judge champion balance and why?
