I still dont have one after 5 years of trying. I used 5 toons this year every day and 6 in Cata, 4 in Wrath, 2 in BC, nothing. I hate that they changed it to drop out of the box, it makes it so much worse. I would have had it long ago if I could just get a group of 5 from the guild to run it until we all have one(5 chances per day per toon for the last unlucky person).
Of course well never get that love rocket...
