You know what I just realized?
This is Call of Duty. Why?
Loadouts. Yeah, Reach had them but they weren't customizable bullshit like this.
And the big kicker? There's no more power struggle for weapons (aside from what, one weapon drop in the game?). Everyone can start with the weapons they use all game instead of having to go find the weapons and fight for map control. Now it's moved to Call of Duty's stupid lone-wolf run-and-gun gameplay.

Sure it's still "Halo" gameplay and gunfights, but it's no longer fully Halo anymore. I really hope they have classic playlists where everyone simply has same weapon start and has to run and grab weapons, like the good old days, instead of spawning ready to go like CoD.
