- Which games count
- Only ranked games (Storm League and Hero League) with 10 players and a winner, each match counted once however many players uploaded it.
- Win rate
- Wins divided by games. Above 52% is marked ▲ green, below 48% ▼ red; with 20 games or fewer it is greyed out because the sample is too small.
- Confidence
- High above 100 games, medium above 20, low otherwise. A dot next to the win rate marks medium or low confidence.
- Tier
- Heroes are ranked by the lower bound of their win rate's 95% confidence interval, so a high win rate from few games ranks lower. Top 10% are S, next 20% A, middle 40% B, next 20% C, last 10% D. Heroes with 20 games or fewer get no tier.
- Influence
- Games × win rate, scaled 0–100 across heroes in the selected range: how much a hero shapes the meta, not just how often it wins.
- Talents and builds
- Talent pick and win rates count every game that reached the level. A build counts games that ended early toward the complete build they started.
