Pick / ban / P+B rates across the ladder. Rank-agnostic — the rank filter is ignored here.
Win RateⓘBayesian-smoothed: (wins + 25) / (games + 50). Reliable even with small samples.
50.6%
Pick Rate
7.2%
Ban Rate
15.3%
ScalingⓘWR slope vs game length. Positive = scales well late, negative = falls off. Practical bounds: ±0.03
0.002
Rank BiasⓘWR slope vs rank. Positive = better in high elo, negative = better in low elo. Practical bounds: ±0.036
0.001
Worst MatchupⓘWorst lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Tail complement to Matchup Spread — captures champions punished by a small number of extremely spiky lanes that MAD averages out. Closer to 0 = no truly bad lanes (safer blind pick). Min 30 games per opponent, ≥5 well-sampled opponents.
-4.3%
Best MatchupⓘBest lane matchup WR minus this champion's own baseline WR, both Bayesian-smoothed. Higher = stronger counter-pick power against the right opponent. Min 30 games per opponent, ≥5 well-sampled opponents.
Master Yi's WR vs enemy top. Sort ↓ for Master Yi's easiest matchups, ↑ for hardest (strongest counters).
Matchup score from Master Yi's perspective. Z-score (mean 0, SD 1) of the weighted composite 0.70·z(delta) + 0.20·z(games) + 0.10·z(WR), pooled across this opponent role. Positive = favorable matchup, negative = hard matchup (strong counter). Same shape as the item synergy / counter pick / duo rankings.Master Yi's Bayesian-smoothed win rate against this opponent. (wins + 25) / (games + 50).Bidirectional matchup delta: avg of Master Yi's gain over its baseline and the opponent's loss against its own. Positive = lopsided in Master Yi's favor. Hover a row for the per-side breakdown.Number of games observed. More games = more reliable WR.
