I'm happy xur is selling it despite having it and here is why: some of my friends with whim u raid, do not have the ghorn, and now, we will be so much better with it then before. But If their is one thing I can tell the people who will buy it this weekend, it's that you are missing out on one of the best feelings in the game, that is to have it pop up at the end if an activity for the first time.
