A twist to Blacks Ops 2 Multiplayer leaked at E3 this week is a change to how you choose your kit, nothing confirmed yet
10 point allocation system replaces primary/secondary/grenades slot system
Guns, attachments, equipment, perks take up allocation points
for example you could have 2 primary weapons which would use most of your points and only have 1 perk.
Or No guns but lots of perks, so you could get a knife kill, steal a gun and make good on all the perks you choose.
If this is true you could load out with 1 gun, lose the flash grenade and secondary weapon and pickup extra perks. Or at least it would be nice..
