League of Legends Crawler displays win-rate, pick-rate, and ban-rate data synthesized from the League of Legends API paired with changes to champions from the League of Legends patch notes. This allows users to view the effect a change has on a champion's strength as well as view all changes made to a champion. Users can toggle rates on/off to overlay different data trends.
