Win Rate by Map
(per-map data as of 2026-09-08)
± avg is Sierra's win rate on the map minus their average across maps, adjusted for each map's overall shift (every hero runs a point or so below their average on the open Hybrids), so it compares across maps and matches the map pages. Kit fit (✓✓ … ✗✗) rates how well Sierra's abilities suit each map's mode and geometry — independent of the observed win rates. Pick a rank to see Sierra's map numbers at your level.
