Key takeaways

  • Current data slightly favors Milio, but the sample is too limited for a strong conclusion: Janna wins 45.5% of 231 games (95% range 39.2–51.9%).
  • Both champions' overall Support win rates predict 51.0% for Janna; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
  • Janna usually wins the lane: 148 gold ahead of Milio at 15 minutes on average (228 games with a 15-minute snapshot).
  • Janna players pick Domination much less often against Milio: 29.5% of their other Support games, 22.1% 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 Janna and Milio 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 Janna'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.

Choices Janna players make noticeably more or less often in this matchup than in their other Support games.

Best Janna Build vs Milio

Usual Janna build (Support)

82.9% win rate · 41 games

Against Milio

Not enough matchup-specific build data: only 8 of 83 Janna games against Milio carried a complete build, which is too few to recommend an item path from. Use Janna's standard build instead.

  • Janna usually completes Moonstone Renewer first, at 13.9 min (median of 150 games).
  • Milio usually completes Echoes of Helia first, at 12.9 min (median of 96 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.
