• Consolidation of the emblem system: All dungeons that dropped Emblems of Heroism or Valor will now only drop Emblems of Conquest. Conquest emblems can be converted into Emblems of Heroism or Valor.
• Season Gear changes: 2v2 ratings are no longer applicable for new season gear. 3v3 and 5v5 ratings are the only applicable ratings for the new season gear.
• Battleground XP: Battlegrounds now offer XP, though the XP can be disabled. Twinks rejoice!
• Isle of Conquest: A new 40v40 battleground featuring keeps and capture points.
• Mount Changes: Mounts are now available earlier throughout the progression, and cost less to acquire.
