Quest:The Valiant's Challenge (Horde) - WoWWiki - Your guide to the World of Warcraft donde dice: "After completing "The Valiant's Challenge", the following quests open up allowing players to repeat the valiant stage of daily quests (steps six and seven) for the other factions with which they have not yet earned the right to champion:
Quest:Valiant Of Silvermoon - WoWWiki - Your guide to the World of Warcraft
Quest:Valiant Of Undercity - WoWWiki - Your guide to the World of Warcraft
Quest:Valiant Of Orgrimmar - WoWWiki - Your guide to the World of Warcraft
Quest:Valiant Of Thunder Bluff - WoWWiki - Your guide to the World of Warcraft
Quest:Valiant Of Sen'jin - WoWWiki - Your guide to the World of Warcraft"

Bueno, el problema es que al hacer el Valiant de tu facción, debería de habilitarse las demás quests de Valiant de las otras facciones y hacer las dailys de nuevo pero de una facción a la vez.

Espero haber sido claro.
Saludos!
