I would rejoice over matchmaking for nightfall and raids, allowing color customization for each individual armor/weapon piece, VEHICLES in PvP, and KILLSTREAKS IN PVP!! Call of duty isn't great when it comes to to gameplay, but in customization and exhilarating PvP play it is king. Also, 6v6 is not epic enough in crucible. I'd love huge open maps with 10v10, 20v20, whatever. Just more than 6v6.
