Emblem System Changes

Both the 10 and 25-player instances of the Crusaders' Coliseum drop a new [Emblem of Triumph].
Any dungeons that previously dropped [Emblems of Heroism] or [Valor], such as Naxxramas or Heroic Halls of Stone, will now drop [Emblems of Conquest] instead. Emblems of Conquest can still be converted to Valor or Heroism.
The Heroic dungeon daily quest will now reward 2 Emblems of Triumph and the normal daily dungeon quest will reward 1 Emblem of Conquest.
