VALORANT Patch 13.08 introduces Map Rating for Competitive and Premier, with every player starting without historical match data. Corrode receives rotation and Mid adjustments, while the Competitive and Deathmatch map pools change.
Map Rating measures map proficiency on a 0–500 scale and assigns a C-to-S letter grade.
Map Rating is available in Competitive and Premier.
Launch ratings begin fresh, with no historical match data included.
Corrode's defender routes into A and B were shortened to aid rotations and retakes.
