Why a team won or lost

The game page compares the two teams on level, takedowns, towns destroyed, mercenary camps, lane XP, time spent dead, hero damage, siege damage, healing and regeneration globes (counted for every hero a globe's effect reaches, so a team's total is several times the number of globes actually picked up). A gap only counts if it is big enough to matter, and each gap is scored by how large it is relative to the totals, weighted by how much that factor tends to matter (team level and takedowns most, globes least). The biggest few become the reasons listed. If the winners were behind on something, it appears as "still ahead, but it wasn't enough".

The weights are judgement calls, not a proven model. Treat the list as a summary of what stood out, not a verdict.

• Biggest contributor (winning team)Each player is scored on their share of their team's hero damage (35%), healing (30%), siege damage (15%), XP (15%) and takedowns (10%), minus a penalty for their share of the team's deaths. A healer's healing share is capped at 40%, since a lone healer would otherwise win every game. If the top two are within 10% of each other, nobody is named.
• Biggest drag (losing team)The player whose deaths, time dead, idling or leaving early hurt most: leaving before the end, being idle for 2 minutes or more, dying 4+ times while making up 30% or more of the team's deaths, or spending 2+ minutes dead with 30% or more of the team's dead time. If nobody crosses a line, nobody is named.

These ignore things the replay doesn't record, like positioning, shot-calling or who was targeted.

The Comebacks column on My heroes shows, for each hero, how often your team won after trailing. A game counts as trailing if, at any point after 5 minutes, your team's total XP was more than 10% below the enemy team's. The column reads wins / trailing games, for example 3/8 means your team trailed in 8 games and won 3 of them. Games without XP data are left out, and a dash means the team never trailed that far. XP is a stand-in for being behind, since a team can trail on XP and still hold a stronger late game, so treat small samples with caution.
