Dear 343,
As a life long Halo Fan, I must say I am very disappointed when it comes to my purchased downloaded content. When your customers purchase a product, are they wrong to expect to use that content in a manner that is expected? Please explain why there is no permanent DLC playlist in Halo4? You can't disenfranchise your customers because the DLC maps are not "popular." Adding the maps to the regular playlist is not enough. Furthermore, those customers who already hate DLC are enraged all the more when playlists start becoming unavailable to them over time. It is a poor tactic to increase sakes and we all see right through you.
Instead, why not remove the restriction on NON-DLC customers and create a single, permanent DLC playlist that has *ALL* DLC maps? This way the holdouts can be gently whoed into DLC and your participating customers can get what they paid for.
