Not only were there 23 new pets added this build, there are legendary battlestones, or at least stones that look like yellow-orange battlestones and MMO-Champion lists them as "icon_upgradestone_beast_legendary.jpg". This is promising!

Is there a guild on Stormrage-US (A) that would allow me to join on a toon to purchase this pet? I'll bring a low level character and earn you some gold as I level up to get the reputation. If you know any guild, mail me in-game (Xtrm-Stormrage) or add my battle-tag Xtrm#1731.
