So, I've waited close to the entire MOP expansion for Invincible to appear in my server's Black Market, but unfortunately the horse wanted nothing with me. For WOD I gave up on Invincible (given how easy he is to farm now) and decided to focus on the Sha's mount but so far nothing.
What about you? What are you looking for in the black market? How long have you been waiting? How long did you wait until you got the last item you really wanted?
