Data Changelog
A record of when and how our matchup data was updated in response to Overwatch patches and new hero releases. Number-only tuning doesn't change matchup reasoning, so we revisit the data when reworks or functional ability changes ship.

Patch response
Season 5: Added Doctrine, updated Sombra (now Support) and the Roadhog rework
- Added the new support hero Doctrine (hero #54). Counters: D.Va (Defense Matrix eats his shots), Genji (Deflect), Cassidy (Magnetic Grenade stops his dash and flight) and Torbjörn. Strong against: Roadhog, Mauga, Ramattra, Pharah and Echo.
- Moved Sombra to Support. Since Hack no longer works on enemy heroes, we removed the 18 matchups that relied on it, and rebuilt her matchups around Hotfix's deployable hacks (destroying Immortality Field, disabling Healing Pylon and turrets) and Cyberspace's Weaken: she now has the edge on Baptiste, Illari, Torbjörn, Symmetra and Bastion.
- Reflected the Roadhog rework: added his edge over Junkrat thanks to the new projectile-absorbing Trash Compactor.
- Removed counters that no longer hold against the new Sombra (Kiriko's Suzu cleansing Hack, Torbjörn's turret exposing her stealth) and updated Tracer's reason against her.

New feature
Merged the checker into the top page
- You can now start the checker right on the top page (no more extra click on a Start button). The old hero-select page (/select) redirects to the top page.
- Fixed a bug where submitting the checker on the English site bounced back to the select screen instead of showing results.

Data audit
Real-match observation: added D.Va → Hazard
- Added D.Va's edge over Hazard based on real-match observation: Defense Matrix eats the burst of his main weapon, Bonespur.

Patch response
Season 4: Added new hero D.Mon
- Added D.Mon, the new tank released Aug 11 (hero #53), with kit analysis and 14 matchups (6 favorable, 8 unfavorable). Since she just launched, only matchups clearly supported by kit structure are included; more will follow as real-match data comes in.
- Reflected the Aug 11 perk swaps (Orisa: Heavy Javelin / Cassidy: Tumbleweed / Jetpack Cat: Purrfect Form). Number-only tuning doesn't affect matchup reasoning, so those are unchanged.
2026.07.30
New feature
Added the all-hero matchup matrix page
- Added a one-page matchup matrix for all heroes (/matrix), with role filters and reason tooltips.
- Hero detail pages now list each hero's perks.

Patch response
July 15 patch follow-up
- Removed Doomfist's edge over Sojourn and updated matchup reasoning for the change to Mauga's single-gun spread.

Data audit
Real-match audit and new-hero matchup expansion
- Audited matchups against real matches and streams: removed weakly-supported pairs and flipped directions where the evidence pointed the other way (e.g. trimmed Sombra's favorable matchups from 22 to 17, reining in "hack beats everything" reasoning).
- Expanded matchups for the newer heroes (Anran, Emre, Jetpack Cat, Vendetta, Shion, Sierra, Mizuki, Domina) over three passes, so every hero now has 11+ matchups.
2026.07.12
New feature
Added kit analysis to hero detail pages
- Hero pages now show each hero's effective range, mobility, hitbox size, playstyle, and per-ability trait tags — so you can see the "why" behind each matchup from kit structure.
2026.07.07
Data audit
Rebuilt all matchup data on kit analysis
- Re-analyzed every hero's abilities with trait tags and rebuilt the matchup data from scratch, following three rules: official ability names only, base abilities as the main rationale (no ult-reliant reasoning), and no pair without a solid reason.
