well as some of you may remember horde used to be able to get a perm ghoul without the talent by talking to a bugged stable master, putting ghoul in and then respec with dualspec and get it out again.
at the updated argent tournament there's a new stable master thats also bugged, called Bognar Ironfoot. Bognar is located at the Argent Crusader tent at the argent tournament.
step 1. get a spec with ghoul talent, and summon ghoul
step 2. go to Bognar Ironfoot
step 3. with your pet out, mount up so it disapears
step 4. Talk to Bognar , drag the "current pet" icon to the "stabled pets"
step 5. Respec to a spec without perm. ghoul talent.
step 6. Talk to Bognar and drag your pet out.
Congratiolations! You've got a permanent ghoul without speccing for it.
P.S. : the reason i'm posting a PTR bug is because i dont think it'll reach live, so you guys can now have fun of it while it lasts.
