Gahz'rooki farm

[Mendelia]

Does anyone have advice on farming Gahz'rooki? I know I can buy him from AH, but it feels like cheating somehow. From Wowhead it looks like Kor'kron outriders are the best bet, but the data is a bit sparse. Thank you!

My sentiments exactly, even though I bought one off the AH I still want to catch my own.
