Duels do not change Elo rating, but award XP (for playing the duel, like a ranked series) and appear in friends' activity.
Social activity
The system records events visible to friends and club members:
- Ranked series finished (with rating change)
- Daily challenge finished (with placement)
- League promotion or drop
- Duel completed
Follow them on the Dashboard, the Friends activity timeline (/friends) and on a player's profile — the profile timeline is visible to friends only.
