- Both champions' overall Mid win rates predict 53.2% for Vex; the result is within the margin of error of that, so this matchup mostly reflects the two champions' general strength.
- Vex usually wins the lane: 405 gold ahead of LeBlanc at 15 minutes on average (77 games with a 15-minute snapshot).
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 Vex and LeBlanc 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 Vex'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 Vex Build vs LeBlanc
Usual Vex build (Mid)
77.6% win rate · 58 games
Against LeBlanc
Not enough matchup-specific build data: only 13 of 53 Vex games against LeBlanc carried a complete build, which is too few to recommend an item path from. Use Vex's standard build instead.
- Vex usually completes Luden's Echo first, at 10.9 min (median of 68 games).
- LeBlanc usually completes Luden's Echo first, at 12.1 min (median of 69 games).
- Skill priority: Q > W > E — 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.
