I remember seeing that exact path on my main right after buying cata... say, isn't that flightmaster a goblin? That would explain SO much...
EDIT: I remembered right. THIS is the flightmaster in question, and apparently she knows just how to do business!

"Hey lady, is it just me or is that gryphon flying in circles?" "Relax, I got best deals anywhere!"
Wonder if the name/flightpath combo is an intentional easter egg...
