Players are now able to act as a mercenary for the opposite faction in PvP whenever your faction is experiencing a long wait time to get into Ashran or unrated Battlegrounds. Agents of the enemy faction will appear at your base in Ashran (Stormshield for the Alliance, Warspear for the Horde) and allow you to enter Ashran or Battlegrounds disguised as an enemy player, and actually fight as the opposite faction.
