It makes sense, though. When you want to have optimal matchmaking and connectivity when playing Call of Duty on either consoles or PC, you need to have all the DLC or no DLC at all. I learned this the hard way when I bought the Reckoning DLC pack for AW last year. I only had that one DLC pack, and so I could not connect to that many people online. Remember that the only people who connect to you online are the ones that have the same DLC as you.

I hate to defend them because of all the shady things they've done, but this really is another smart marketing move by Activision.
