1) Return of the Arbiter and his Elites (the latter in either [i]Halo 3[/i] or [i]Anniversary[/i] armor) 2) Return of Playable Elites 3) Functional-looking, [i]Reach[/i]-style armor, though slightly less worn 4) Return of Invasion, minus the forced color 5) Toggle Covenant language (English, Sangheili, etc.) 6) Return of furry Brutes and their nifty technology 7) Original Mark VI for the Master Chief 8) Weapon models instead of weapon skins (because I like the Plasma Rifle better than the Storm Rifle) 9) Return of the Scarab, V1 and V2 10) Return of the Elephant and Mammoth 11) Return of the Falcon, preferably with passenger seats 12) Objective maps where flying or transport vehicles are neccesary (Scene: a bunch of Banshees flying around a Falcon, the Flag Carrier cowering behind the Elite on the turret) 13) 24 players per lobby 14) Removal of Tactical Packages and Support Upgrades 15) Black on the color pallette, plus an undersuit that didn't match the primary color, because I haven't yet met anyone who was pleased with that 16) Alert Carry enabled by pressing down on the D-Pad. Animation looks like [i]Reach[/i]'s, functions on XBox Live 17) Toggle first- and third-person assassinations, driving, and gameplay 18) Bring back the SMG. Not for dual-wielding, but buff it up a tad to make it useful. 19) ODST helmet and shoulders that look right 20) [i]Halo 3[/i]-era Marine armor, with [i]Reach[/i]-era ODSTs Frankly, though, I'd just be happy if they looked at [i]Reach[/i] and [i]Anniversary[/i] for art design, simpler Personal Loadouts, and playable Elites.
