Riot shuts down ‘unhealthy’ win-rate data through updated API policy in TFT Patch 13.12
Riot Games is set to limit the data that third-party organizations can access within Teamfight Tactics Set Nine Runeterra Reforged and future sets, allowing the meta to develop organically.
Over the past couple of TFT sets, an increase of third-party sites showing win-rate data for Augments at each Stage has increased. Data mined this way isn’t necessarily a bad thing, but it can skew the set meta while discouraging player choice, according to Riot in the Patch 13.12 notes. The API change will go into effect on June 19 and will affect Legend win rates as well at each Stage.
