The World of Warcraft website announces Blizzard is working on a new PvP Mercenary Mode that will allow players to participate in Ashran or unrated Battlegrounds without having to wait through long queues. Word is this will switch you to the appropriate faction on the fly:

They say, “Keep your friends close, and your enemies closer”—and soon, you’ll be able to do just that.

In an upcoming patch, we’ll be adding a feature that allows you 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 in your base in Ashran (Stormshield for the Alliance, Warspear for the Horde). These agents will allow you to enter Ashran or Battlegrounds disguised as an enemy player, and actually fight as the opposite faction.

When you compete as a mercenary, you’ll still earn all the same rewards you would have by winning or losing as your own faction (with the exception of faction-specific achievements). You’ll also have your race automatically changed into one appropriate for the opposite faction while you’re still inside the Battleground or Ashran. Perhaps most importantly, however, you’ll experience much shorter queue times, as our matchmaking system will be able to fill up groups much quicker!

Our goal with Mercenary Mode is to allow players who want to participate in Ashran or unrated Battlegrounds the ability to do so without having to wait through long queues, while still maintaining the spirit of the core Alliance vs Horde fantasy. We’ll be testing this feature soon on the Public Test Realm, and look forward to hearing your feedback!
