If you want dragon mounts, WoW is choc full of them. There are all kinds of dragon mounts, including one from four of the five main Dragonflights, the conspicuous gap in the collection, of course, being and Emerald drake. Now, if you're like me, you've been dreaming of a green dragon mount since you knew dragon mounts were a thing. Thus far, us green drake mount enthusiasts have been left out in the cold. Until Warlords of Draenor, at least, it seems.

If you've got a particularly strong opinion on this meta-achievement one way or another, be sure to let Jonathan know via twitter or the official forums. His tweet did ask for feedback, after all!
Update: I somehow missed the tweet yesterday that clarified that the Sandstone Drake part of this meta will be replaced with the Purple Netherwing Drake for quality of life purposes. In my opinion, this is a nice change and will make the collection aspect significantly more straightforward!
