WEAPONS
-Assault rifle: I'm hoping for this one to be much longer range. seriously, it's your main weapon and you can't even shoot across Guardian.
-Battle rifle: The battle rifle needs to be less of a power weapon. make it so it's not as much of an all-around powerhouse and more of a mid range weapon.
-Magnum: Replace this with the faster firing more powerful ODST version.
-SMG: less recoil, more Range, more power. let's go ahead and just use the ODST version with a scope.
-Rocket Launcher: keep same
-Shotgun: keep same
-Sniper rifle: keep same
-Missile Pod: completely remove. i don't like lock on. it's practically impossible to dodge on open maps.
-Sentinel beam: less power, less lag.
-plasma sword: keep same.
-Plasma pistol: make it so the energy doesn't drain that fast when your charging it.
-Plasma rifle: way more power. this one needs to be up there with the assault rifle.
-Needler: Less power, less lock on.
-Fuel rod gun: campaign only. this ones pretty much useless anyways.
-Beam rifle: Campaign only. let the guys in mm have the sniper. the jackals can keep this one.
-Carbine: more of a mid range weapon. more accurate.
-Grav hammer: keep same
-Spiker: More powerful.
-Mauler: keep same.
-Brute shot: not sure.
-More mid and long range weapons! i cannot stress this enough. give me something like a crossbow, or something i can use to take down a sniper at least.
GRENADES
-all same.
VEHICLES
-Gauss wharthog: slower rate of fire on the turret. this is always the place i see people getting killionares with.
-Banshee: hover ability.
-Hornets: no missiles.
MULTIPLAYER:
-12 Vs. 12 for now. 20 on 20 would be nice though.
-Firefight matchmaking system.
-infection playlist.
-community map playlist.
-new ranking system.
-harder ranking system. (this time, you have to get to 150 instead of a 50.)
Campaign:
-longer.
-much fuller.
-creativity. (we need something new, something special. like halo: CE.)
Forge:
-much more in depth (i have no doubt that bungie will do this.)
-no money limit
-faster merging.
-interactive objects (elevators, openable doors, switches, all that stuff.)
