1. EQUIPMENT: Bring back the halo 3 EQUIPMENT as armor drops, in addition to the halo reach and halo 4 armor abilities. Have both armor abilities and equipment in the custom loadouts. On the controller the equipment could be a up or down on the D-pad. There Could also be a armor mod, tactical package, or support upgrade that will allow you to carry two.
2. SMG: Bring back the SMG for custom loadout use and dual wield.
3. DUAL WIELD: Bring back dual wield. If dual wield is used in custom loadouts (I belive it should as a tactical package or support upgrade) all secondary weapons should be dual wieldable and a few primary weapons including the SMG and atleast one primary covenant weapon and one primary forerunner weapon if not more. In the custom loadouts if dual wield is chosen there could be a tactical package or support upgrade (wichever is the one dual wield is not) that would allow you to use a primary weapon like the SMG. In game play to avoid overpowering dual wield uou, like in halo 3, would not be able to use uour armor ability, equipment, grenades, or mele atacks untill one weapon is droped. Even if dual wield is not in the custom loadouts uou should be able to grab a weapon off the ground and dual wield it.
