Is there any reason why Bungie can't make a new combined arms game mode that lets 2 full Raid teams face off against 2 full Raid teams on a full sized planet? Imagine 12 vs 12 on the EDZ. Each team would spawn in on either side of the map with 2 tanks and 4 pikes. They would race to take over different control points in an epic battle. You could also have cool pickup weapons hidden around the map that would drop special and heavy ammo for other Fireteam members when you get kills with them.
