Halo Game Modes?

My opinion i wish they could do a game mode where you could fight as a team vs large army of covenant. Make it something like battlefront but you can fight air battles against covenant ships and such. A giant battle to see who can get the most kills and you fight alongside marines and sgt johnson. I think it would be a great idea but who knows what they will think of next. Also where will the story go next? They need to make a game where the AI are just boss and not nooby fighting computers. They could actually accomplish something for a change. This could potentially give gamers more of a challenge than easily fighting through the campaign and win the game. Let the AI roam freely around the map and some of them won't be in the exact same place every time you die. Here are some images from the halo games, but somewhat what the game mode could look like but better graphics of course.
