Estimate, not insider information
Will Rat King get nerfed?
Our next-balance-patch estimate increases with above-average win rate and pick share. It has not been calibrated against historical nerfs and is not a reliable forecast of Valve’s decisions.
Inputs: win 57.58%, pick share 4.28%. Minimum 1,000 observations; otherwise no reading. Patch history below is evidence, not an input to the estimate.

Every explicitly attributed change found in the 26 available archive entries. This is the available archive, not a claim of complete lifetime coverage. Linked-only announcements may omit change text.
