Tamed just recently.
Really helps if you have access to a second account.
1. On the 2nd Account make a level 110 Class trial on a low population server ( I did on 3 separate servers).
2.Fly them out to Sholazar Basin and park them there. (You have 3 hours of playable time on each Trial Class. I found I could log one in send my Hunter an invite so my Hunter would phase to the other server, then I would log the Trial Character out which I camped/circled the Basin. This still took a while, however if your on a high population server there are usually multiple horde and alliance camping each spawn point. This way I found with the low pop/RP servers I was often the only person of my faction in the basin.
By the time Loque spawned I had also tamed King Krush twice, and killed him twice, and tamed the bird once and killed it twice. So you still have RNG to deal with on which rare actually spawns. Quite often I would kill/tame the rare on one server to log into the next and the rare was on the new server also. Wether this was a complete fluke or not who knows.
I'm trying the same method with other Sought after rares.
Hope this helps any other hunters looking for a particular rare.
