- Both champions' overall Mid win rates predict 50.6% for Kog'Maw; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Kog'Maw players pick Health (defense) much less often against Yone: 44.9% of their other Mid games, 18.2% here.
How we calculate this
Games: ranked Solo/Duo and Flex games on the North America server from the patch shown. Remakes (games under 5 minutes) are excluded.
A game only counts when Kog'Maw and Yone played the same position on opposite teams, so roaming, lane swaps within a team or a champion merely being in the same game never count as this matchup.
The 95% range is a Wilson score interval. Confidence comes from how wide that range is: within ±3 points is very high, ±5 high, ±8 moderate, anything wider low. Below 20 games a matchup is not classified at all.
Expected win rate combines both champions’ win rates in this lane (same games and filters) with the log5 formula: E = A(1−B) / (A(1−B) + B(1−A)). Matchup effect = observed − expected.
"What changes" compares Kog'Maw's choices in this matchup with the same champion's other games in the same lane, and lists a change only when it is at least 3 points and statistically significant (two-proportion z-test, |z| ≥ 2, 20+ games).
Results are not split by rank: the sample per rank is too small for honest per-rank matchup numbers.

Best Kog'Maw Build vs Yone
Usual Kog'Maw build (Mid)
57.1% win rate · 56 games
Against Yone
Not enough matchup-specific build data: only 5 of 15 Kog'Maw games against Yone carried a complete build, which is too few to recommend an item path from. Use Kog'Maw's standard build instead.
- Skill priority: usually E > Q > W; against Yone, W > Q > E.
Builds are ranked by the lower edge of their win rate range, not the raw win rate, so a build seen in a handful of wins never outranks a proven one.
