Call to Arms

In patch 4.1 Blizzard introduces Dungeon Finder : Calls to Arm. a new system intended to lower queue times. Call to Arms will automatically detect which class role is currently the least represented in the queue, and offer them additional rewards for entering the Dungeon Finder queue and completing a random level-85 Heroic dungeon.

 Any time the Dungeon Finder queue is longer than a few minutes for level-85 Heroics, the Call to Arms system kicks in and determines which role is the least represented. In the case of tanking being the least represented role, the "Call to Arms: Tanks" icon will display in the Dungeon Finder UI menu where class roles are selected, and will also display on the UI when the queue pops and you are selected to enter a dungeon. Regardless of your role, you'll always be able to see which role currently has been Called to Arms, if any.

Call to Arms is meant to lower wait times by offering additional rewards for queuing as the currently least represented role. To be eligible for the additional rewards you must solo queue for a random level-85 Heroic in the role that is currently being Called to Arms, and complete the dungeon by killing the final boss. Every time you hit these requirements (there is no daily limit) you'll receive a goodie bag that will contain some gold, a chance at a rare gem, a chance at a flask/elixir (determined by spec), a good chance of receiving a non-combat pet (including cross faction pets), and a very rare chance at receiving a mount. The pets offered come from a wide variety of sources, and include companions like the Razzashi Hatchling, Cockatiel, and Tiny Sporebat, but the mounts are those specifically only available through dungeons (not raids), like the Reins of the Raven Lord from Sethekk Halls, Swift White Hawkstrider from Magister's Terrace, and Deathcharger's Reins from Stratholme.
