Source: Nexus Lab rules over the official ability text, League of Legends patch 16.21.1. Each champion of the class is compared with Yuumi one by one; the counts come from those rules, not from match results, so they are not win rates. Strong, even and weak compare the number of champions ahead and behind. Lanes are the lanes each class usually plays (Riot ships no lane data per champion), not play rates.

What no source gives us
- Win rate, pick rate and ban rate. Riot publishes none we may print (the Riot API cards are switched off) and no third-party statistics site is read, so none is shown.
- Popular builds. Riot publishes no builds: the items and runes in Build & Runes are a fit to the kit, not a popularity ranking.
