After seeing how much of a grind the new Kai'sa "chroma" looks like, I decided to do some math in case Riot decides to do the same (in my opinion) bullshit with the Ahri skin. I thought I would share.

For my calculations, I will assume a 55% WR (my WR in normals overall) and a score of A-, A or A+ for every match. The pass will be bought the first day to get access to the first win of the day tokens (15) as soon as possible.

So, first of all, Kai'sa costs 2500 tokens. You get 360 for the missions, and 200 for the pass. This means you only need 1940 tokens via the Worlds Pass.

First of all, we need to calculate the amount of games needed to reach this goal.
