Patch 6.1 BugsPlayers are currently reporting that their Swift Zhevras and Argent Warhorses are going missing. Sometimes they seem to come and go. Please follow the official bug thread for the latest info.
Patch 6.1 Mount HighlightsPatch 6.1 has landed. At least three new mounts should be available immediately:
The spectacular Voidtalon of the Dark Star, which resembles a purple version of the Flametalon of Alysrazor. While its source is not yet confirmed, this mount has been reported to be obtained by entering a randomly-spawning smoky portal. It is possible that the portal will only appear in higher-level areas. The portal leads to a mini-instance called The Edge of Reality, containing a dead NPC - The Last Voidtalon - and a single, lootable egg which teaches the mount.
Later in Patch 6.1...
A glowing, purple panther known as the Mystic Runesaber. It's set to be a new In-Game Store mount, but we don't yet know when it'll be released.
Ongoing Armory Bugs. Our mount import service is still unable to find certain new mounts. These are due to issues with the Armory at Blizzard and there's sadly nothing we can do to fix them sooner. As a temporary measure we've enabled manual addition of the Champion's Treadblade, Chauffeured Mechano-Hog and Felfire Hawk via your account page. The Acherus Deathcharger has also been missing for some years. Please let us know if you find any others that are still problematic. Thanks!
