All i want I
A better campaign
Arbiter Return
And Remake Forge World from Halo Reach
No rank requirements for emblems
Make So you can play as an elite or Promethean in custom games
And bigger scaled maps with more game modes
And dont put in the different game modes and take them out In the newest patch
Dual Wield in Multiplayer and campaign
Bring the flood back into the campaign(besides they had their own game mode its only fair)
And more vehicles
