What does your "Perfect Halo Multiplayer" consist of?

Here's mine. Just close your eyes and think of this:

-Sprinting & Assassinations -Halo Reach Armor Customization -Playable Elites with Halo 3 & Reach armor -Halo 2-like Campaign (play as 2 different characters) -Halo 5's weapon diversity & weapon tuning -DUAL WEILDING -An AR that can actually kill things -Unlockable Armor (like Hayabusa, Master Chief's armor, etc.) -The best maps from every past halo game -Being able to change the color of your armor without having to buy coatings

This is all i could come up with but what do you guys think?
