If you still need some rare pet tames, you should get to know someone on a low-population role-playing player-vs-player realm (A.K.A. LowPop RP PVP).
I had a friend from such a realm invite me to group. I phased to his realm. Then suddenly instead of more than a dozen level 90 hunters looking for Loque, there was just me. Oh! And he's right there because nobody has tamed him. Port over and grab Ghostcrawler. All done in less than 10mins.
My mind was completely blown. I had been after those pets off and on most weeks of this year.
