Other than player customization players should have more customization like the ability to change the HUD color and what side you hold your gun. Other things like in forge choose monitors, sentinels, engineers, etc. and another thought why not have more species for different game modes like marines with about the same amount of customization as a spartan. Let have customizable elite armor and brutes shoulders, chest, helmet, eye/visor color, wrist, hip, back. And grunts, hunters, halo 4 enemies.
Thoughts, suggestions, trolls.
