Some things I would like to see in the armory off the top of my head:
* Higher quality stun / explosive ammo.
* Increased Vulture Time
* Trap Immunity
* Start with a Hypno-Knife
* Team Explosives Refills Venom-X Ammo
* Increased Duration on Class Abilities
* Claymores / Betties apply Incendiary Damage
* Extended Mags on All Guns
* Spawn with a Gun (Weapon Locker Style)
I do have a hunch that those five classified abilities may have something to do with spawning with a Venom-X, but that's just me.
