- Senna usually wins the lane: 540 gold ahead of Nami at 15 minutes on average (207 games with a 15-minute snapshot).
- Nami players pick Health Potion + Health Potion + Stealth Ward far more often against Senna: 52.6% of their other Support games, 59.9% 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 Nami and Senna 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 Nami'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.

Against Senna
54.5% win rate · 22 games
Limited sample: 22 of 101 games finished this exact core, so treat it as an observation rather than a recommendation.
- Nami usually completes Echoes of Helia first, at 12.4 min (median of 93 games).
- Senna usually completes Statikk Shiv first, at 14.2 min (median of 88 games).
- Skill priority: W > E > Q — the same as usual.
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.
