Rank tiers:

Rank tiers are the named divisions used to group players within Overwatch 2’s competitive ranking system. They show a player’s general skill level and provide a clearer milestone structure than a single hidden number.

In Overwatch 2, rank tiers help determine matchmaking and track competitive progress, with players moving up or down as their performance changes over time. They also give context for where a player stands relative to others in Competitive Play.
