Hero performance ratings

The replay doesn't say how well someone did their job, so we compare their numbers with other players on the same kind of hero. All numbers are per minute so game length doesn't matter, and games shorter than 5 minutes are ignored.

• Tanks: damage taken, time spent crowd-controlling enemy heroes, takedowns, and deaths (fewer is better).
• Healers: healing, teamfight healing, clutch heals, and deaths (fewer is better).
• Ranged assassins: hero damage, takedowns, experience contribution and deaths.
• Melee assassins: hero damage, takedowns, solo kills and deaths.
• Bruisers: hero damage, damage taken, siege damage and deaths.
• Supports: experience contribution, siege damage, hero damage and deaths, compared only with the same hero because they play so differently.

A measure a hero rarely produces (such as solo kills on a hero who almost never gets them) is left out for assassins, bruisers and supports. Gall, Abathur and The Lost Vikings aren't rated because their numbers are split between players or bodies, or come mostly from a summon.

For each measure we work out the share of comparison games they beat, then average those. 80 or more is Excellent, 60 Good, 40 Average, 20 Below average, under 20 Poor. We compare with the same hero once there are 25 or more games on it, otherwise with every hero of the same class, and show nothing until there are 30 games to compare with.

This ranks output, not decisions. A tank who soaks damage by standing in the wrong place scores well; a healer who is ignored by a team that never gets hurt scores low. Only tanks and healers can earn an anti-award from this rating.

A card only appears when there is enough to compare. You won't see one if:

• the hero is Gall, Abathur or The Lost Vikings;
• it's a support and we have fewer than 25 games on that hero, since supports are only compared with themselves;
• fewer than two measures have data, because the game is under 5 minutes, stats are missing, or the hero rarely produces them;
• there are fewer than 30 games to compare with.

These anti-awards use this same rating. A tank whose rating is under 20 gets Paper Tank, and a healer under 20 gets Missing Healer. Nothing else is different between them: the role decides the name. At least two measures must have data, so a game with missing stats gets neither.

• Who they're compared with: the same hero once there are 25 or more games on it, otherwise every tank or healer, and only when there are 30 or more games to compare with. A hero we've seen rarely is judged against a mixed group that plays quite differently.
• Because the rating is a ranking, some games will always land in the bottom band, even if nobody played badly. These awards are for fun, not proof of a bad game.
• The comparison group is made of the games stored so far and changes as more are uploaded, so a game's result can differ slightly depending on when it was worked out. Awards already given are never taken away.
