[Halo 5 and 6 plot ideas?]

For halo 5 you should be able to play as a grunt

 

What is a didact! is he that guy in a sphere

 

These are me and my brother's idea:

make the knights and crawlers playable in multiplayer

bring back the unsc falcon as a playable vechicle

add the locust as a playable vechicle

put blue team in the campaign so we can work with them

replace thruster pack with armor lock

put cortana back in the game

add the arbiter and elites back (the allies)

They should also add grunts as playable chracters and make them cuter
