I would love to see the brute weapons come back…the old plasma rifle…and able to use the promethian swords.
I’d like the choppers back.
Playable Elites.
Hornet/ Falcon.
Invasion
Dominion
Needle Rifle
Plasma rifle
Concussion Rifle
Grenade launcher
Covenant themed props
Full Armor customization
A finished game upon release
A classic slayer gametype. (No thrusters no clamber etc.)
Bigger warzone maps and more interactive AI.(like titanfall where AI would run round the map and try to kill players.
Ranked team snipers first please 
They need to add some fixes, not content. Well they need more content too… People are obviously starting to put the game down and give up on it. I am hopeful 343 can turn it around and bring people back though. (I am not going to go into detail here, as I have already made posts with my specific complaints.)

They should also increase the radar range.
