Champion Role Details

Current Model Parameters

The five role segments sum to each champion's overall pick rate; all use the same 84-game denominator. Upper bars are predictions and lower bars are actuals, with identical role colors. Bans have no observed final role, so ban rate and draft presence use aggregate bars. Mean position is conditional on being picked: global pick rank 1–10 and full draft step 1–20.Full Model Report · Mainland Chinese names and titles follow Tencent Mainland China Website; portraits come from Riot Data Dragon 15.20.1 and are stored locally.
