Matchups

No lane opponent has come up 60 times yet. Counters need a bigger sample than builds do — a few points either way is noise until then.

Counted from 53,272 ranked solo queue matches played on patch 16.19 by Emerald 2+ players on EUW, read from Riot's match API. Percentages are shares of the games in this lane, not of the builds listed — so three rows adding to less than 100% means the rest of the games did something else. Win rates are hidden where there are too few games to state one.
