I don't see anyone talking about it, so I'll start one...
If you don't know what I'm talking about, go here and read this: http://www.wowhead.com/news=256931/p...ounts-and-pets
Today (patch day) there are two of the four world quests available. I was able to do both and get the pet from both.
I accepted and completed the quest to level my snowfeather falcosaur pet to 25. (3-4 pet trainer battles as per usual.)
When she dinged 25, she emoted that she was "tired after her big adventure" and laid down for a moment and slept. She then popped back up, but didn't yet give me a quest, so I'm guessing her quest chain is time gated.
Overall, very cute!
Since you can only have 1 pet out at a time, you really only have to level the 1st one to 25. Then when you finish its entire quest chain, you can use the Ultimate stone you get to level the next one to 25, and continue on to quest to get the next mount. If you are like me and burned yourself out on pet battles in WoD (I did 9 characters per day in the pet menagerie plus the pet trainers each day, whew), this is a nice bonus.
A couple of notes - suggest making a macro "/target orphan". Then you can stick a boss marker on it and that makes it easier to find, as they are small and these areas are full of people and chaos right now. The one in Aszuna is almost right in the middle of the quest area. The one in Highmountain was NOT in the quest area - it's off to the south at 32,28 near the entrance to the feltotem village, pretty far from any of the quest falcosaur spawns.
