Patch 16.14 · LeBlanc mid

LeBlanc measures best beside Pantheon in support, and worst beside Caitlyn.

Beside Pantheon, LeBlanc's win rate moves by +3.3 wins per 100 games (range -3.1 to 9.8) 72 games Pooled against LeBlanc's own average.

Beside Caitlyn: -3.3 wins per 100 games (range -9.6 to 3.0) 87 games Pooled .

The number is a delta against LeBlanc's own average, because a high win rate beside a strong champion is that champion's strength, not the duo's.

Who does LeBlanc work with?

Delta in wins per 100 games against LeBlanc's own average, the 8 best first. The bar under each figure draws that row's own 95% range on one scale, from 9.7 wins per 100 games below LeBlanc's own average on the left to 9.8 above it on the right. The tick is our estimate, the short line is zero, and a hatched bar is one whose range covers zero or spans most of the scale: those games do not pin the pair down.

A pair needs 50 games together before it is estimated, and each estimate is pulled toward LeBlanc's own average first, so a thin duo cannot crown itself. The verdict reads the delta range: beats only when the whole range clears zero. A delta bar that covers zero stays stone: unclear yet. Teammate pairs share fewer games than lane opponents, so this list runs shorter than the counters page.

138 more teammates, with 3,346 games between them, sit under the pair floor: counted, not listed.

How LeBlanc's own games read

The average every delta above is measured against.

LeBlanc won 724 of 1,448 games recorded in mid on patch 16.14. As an estimate: 50.0% (range 47.4-52.6) 1,448 games Measured .

What a delta cannot prove

A delta is not proof: the players who queue together differ from the players who do not, and nothing here holds that still.

LeBlanc needed 1,000 recorded mid games before this page existed at all. Every floor and constant is on the methodology pages.

These numbers come from 108,616 ranked games we recorded on EUW, Korea and NA, found by following Diamond players and the people they play with. That is not every rank and it is not every region. Everything on this page is patch 16.14. Counted up to 24 July 2026.
