Duo compatibility
Some players just click together. /compatibility checks whether the numbers agree. It compares two players across the matches they've shared on the same team.
What the card shows
- Preferred roles for each player, weighted by actual playtime.
- Best and worst maps and enemy matchups for the pair.
- Results together versus apart: do you win more as a duo than separately?
- Team ban tendencies: which heroes your team bans most in your shared games.
- Best hero pairings, such as a Duelist plus Strategist combination that keeps winning.
By default the card uses all-time Competitive history. Add season: or mode: to narrow it down.
Which matches count
Only matches where both players were on the same side count as duo games. Lunar finds them in either player's history and counts each match once. Games where you were opponents never count. Being on the same team doesn't prove you queued together, though. You may have been matched by chance.
Proving a hero pairing
Players swap heroes mid-match, so "we both played those two heroes in that game" isn't enough. The match data has each player's time per hero but not the exact moment of each swap. So Lunar works out the guaranteed minimum overlap:
minimum time together = hero A time + hero B time − match length (never below zero)
For example, in a 10-minute match, if one player spent 8 minutes on their hero and the other spent 7 minutes on theirs, they must have overlapped for at least 5 minutes. A pairing only counts for a match when that proven overlap is at least 60 seconds. Matches where the overlap can't be proven still count toward your overall duo record, just not toward any specific pairing.
The card shows the minimum minutes together and how many shared matches back each pairing. Pairing win rates are whole-match results, not results measured only during the overlap.
Reading small samples
Pairings with at least five games rank ahead of smaller ones. Below that they're ranked by the Wilson lower bound and marked preliminary. Map and opponent entries with few games carry a † marker. See how Lunar ranks heroes for why.
Getting a fuller picture
Lunar can only analyse matches it has recorded. If your duo card looks thin, more shared history fills it in. Running an update backfill for each player adds older matches to the sample.
