Brackets, ratings and maps

  • Brackets: 1v1, 2v2 and 3v3, each rated or unrated (same rules, no rating change). Duels in town are unrated 1v1s.
  • Ratings are kept per class and per bracket and start at 1500. Since patch 0.21 a win gains at least 16 up to 1500 (tapering to 6 at 2500 and 2 at 3000), and a loss costs at most 18. Guests appear on the leaderboard once they save their progress.
  • Arenas: Nagrand Ring (four pillars), Ruins of Lordaeron (a tomb in the middle) and Blade’s Edge (a log bridge over a gravel pit; height matters, the bridge blocks sight).

Diminishing returns

Crowd control of the same category within 20 sec of the last one ending lasts full, then half, then a quarter as long; a fourth is resisted. Polymorph, Fear, Cyclone, Sap, Hex, Repentance, Blind and Seduction hold one target at a time: casting one on a new target frees the last.
