This is probably your only decent point.
- It doesn’t apply to healers. If healer leaves, then the other healer would have 6-0 (and fairly, because the other healer, his only competitior, conceded all matches).
- They could have gotten few points (but you’re right, not many).
- Loser can still have 1-2 or 1-3 before leaving, meaning somebody might be able to get actually 4 wins or so.
