Didn't have the Ominous Flame, tried all other strats that I had pets for and finally leveled my Corrupted Blood to try this one. Took several attempts before Cataclysm landed but finally got it. Thank you!
This startegy requires luck ... the same kind of luck to find a gold coin in the middle of the desert, want to get frustrated from pet RNG, this one is the way to go. You will have fun for houres thill you might get a win
