Classes & Team Compositions

Champions are pooled into every class they carry, so multi-class picks (Alistar is Tank and Support) count in each — pick rates add past 100%.

The same table, but each champion is counted once under its primary class — the first tag Riot lists. Pick rates now sum to 100%, and each row describes only the champions whose identity is that class.

De-mirrored drops the games where the enemy fielded the same number of that class — those split one win and one loss by construction, pulling the raw rate toward 50%. It reads as “you had this many and they didn’t”: 0× de-mirrored means you had none while they had some.
