I have a feeling not everyone wants to play halo 2 for every subsequent halo game.
I certainly don't. What I don't want is fundamental changes to Halo gameplay. Think about this, aside from slight changes to jump/movement, fall damage/health, the big difference in gameplay between Halo CE, Halo 2, and Halo 3 is dual wielding or added equipment. That's it. The rest were changes in weapons, vehicles, aim assist, strafe speed, movement, gameplay modes etc.
Now we've gone from Reach where we got assassinations and armor abilities including sprint/jetpack/armor lock, to Halo 4 where we got universal sprint, friendly fire off, instant respawn, killcams, loadouts, perks, join in progress, global map ordnance, personal ordnance, different armor abilities, to now Halo 5 where we're getting universal thruster pack, universal sprint, universal ledge climbing/clamber, universal ground and pound, universal frontal/behind Dash/Charge Slam, Aim Down Sights/Smart Scope, two primary weapons, plus we don't even know what they have planned for Big Team Battle.
So you can see why fans of the earlier games want more of what they got, than what they've been getting the past four years. Once Halo 5 releases, we'll basically have had as much radically changed mainline Halo than classic mainline full release Halo.
