pick rate
MatchmakingDefinition
Pick rate is the percentage of matches in which a champion, hero, or weapon is selected. Pick rate combined with win rate determines whether something is meta. Sites like Op.gg, Mobalytics, and Tracker.gg surface pick rates per rank tier — a champion might be Diamond-meta but pub-trash, or vice versa.
Example
"Yone's pick rate spiked to 18% after the rework." Players are selecting the champion much more frequently after a balance change.
