We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
I believe this is because Black Ops 2 stats were recorded through Call of Duty Elite and Ghosts is through a completely different system. Also CoD Elite got officially shut down last week, so you're too late to get it.
