How did you work for it? There is no specific play list to play that the Last Word is the prize for completion. Now the players that play the Nightfall and weekly heroic strike play list do earn rewards that allow player to spend them how they see fit. This whole I earned it by random drop is so back asswords. Your walking down the street and find a $100,000 dollars and go and buy a Ferrari and then complain that the guy who works a 40 hour a week job and makes payments on his Ferrari didn't earn it and that the Ferrari dealer has cheapened your car.
