Griffball, splasers, hockey... COME BACK PLZ

Hey 343i, im a big fan of the halo franchise and i love what you did with halo 4. But When are you gonna add the rumble pit playlist? or griff ball playlist? i sorta get tired of killing countless numbers of Spartans in slayer and need a break from it. Yes there is the option of custom games but not everyone has friends to play with. So can you guys please add a playlist for this kind of chaotic fun? Just letting my opinions go.
