Coverage

  • —Time range: February 2015 – April 2026
  • —Patches: ~5.3 through 16.7
  • —Champions: All champions available during each patch
  • —Roles: top, middle, bottom, support, jungle
  • —Granularity: ~biweekly samples aligned with patch cycles

Notes

  • —Champions added after 2015 have data starting from their release patch.
  • —Some champions appear in multiple roles (e.g. sylas_middle.json, sylas_jungle.json).
  • —Pickrate/banrate values may be absent for very early patches on low-popularity picks.
  • —Patch naming: seasons 15 and 16 (years 2025–2026) use season-based numbering (15.1, 16.3) rather than year-based (25.S1.1, 26.3).
