About OverwatchBrain

OverwatchBrain turns Blizzard's official Overwatch stats into tier lists, trends, and per-hero breakdowns. It currently tracks 50 heroes across 28 maps, covering both competitive and Quick Play.

How Tiers Work

Each hero gets a composite z-score built from two things:

  1. Win rate is the main signal. We compare every hero's win rate to the overall average; heroes well above the mean score higher, heroes below it score lower.
  2. Pick rate acts as a small secondary boost (15% weight). A hero that's picked a lot gets a slight nudge upward, but a low pick rate doesn't count against a hero since it could just mean they're niche or frequently banned.

The composite score gets bucketed into five tiers:

S Well above average
A Above average
B Average
C Below average
D Well below average

Tiers update every time new data comes in, so they track the live meta. They're also relative: a hero can move tiers even if its own win rate stays flat, because every other hero's performance matters too. See the current rankings on the Tier List page.

Estimated Rank Filters (+)

Selecting a rank like Gold shows stats for only Gold players. Clicking the + badge on a rank switches to Gold+, which combines stats from Gold and every rank above it.

Blizzard only publishes rates per rank without player counts, so the combined figure is an estimate. Each rank is weighted by its approximate share of the player population:

Bronze Bronze ~8%
Silver Silver ~18%
Gold Gold ~26%
Platinum Platinum ~22%
Diamond Diamond ~15%
Master Master ~7%
Grandmaster Grandmaster ~4%

The ~est. label appears next to the Rank filter as a reminder whenever a "+" tier is active. Patch trend win/pick rates are averaged the same way.

Data Updates

Stats are pulled automatically from Blizzard's official data and cover all competitive ranks (Bronze through Champion) plus Quick Play, broken down by map and role.

Frequently Asked Questions

Where does the data come from?

Everything comes from Blizzard's official public stats for Overwatch. No third-party APIs, no user-submitted data.

How often is data updated?

Regularly. The footer on every page shows the exact date of the last data pull.

Why is a hero ranked differently than I expected?

Tiers reflect aggregate performance across all players at a given rank, not pro play or coordinated team potential. A hero can feel great in your matches but sit lower if the wider player base struggles with them. Try filtering by rank on the Tier List page to see how things shift at different levels.

Can I see stats for a specific rank?

Yes. Both the Heroes and Tier List pages have a rank filter (Bronze through Champion), so you can see how win rates and tiers look at your skill level.

What maps are included?

All 28 maps in the current pool. Individual hero pages have a full map-by-map breakdown.
