I pretty much always use Armour Lock, the only times I don't is when I need to use sprint, which isnt that often. Sometimes I simply pop into it, wait to see the animation of enemy reloading, unlock and kill him. Or when I see an enemy in armour lock, I walk up to them, wait a little then pop MY armour lock on, they usually freak out and drop theres, which is when I drop mine and melee them and kill.

Importance is variation, and also I try to time it so I always have 1 armour lock saved (Like I only use armour lock, till the circle is half full), then I can always pop in.

Playing with Korn and Masters, Masters and I are beast with AL, he pop in, screams down mic, and I get easy kill. Or sometimes, I throw a grenade, just as its about to go off, he drops into armour lock, hits enemy and I get easy kill.

So its 19th October, 10am PST (6pm for me), no updates

Also, sometimes I go to select stuff from my Local Files thing, and its grayed out (meaning no device is selected) but theres no way to select it...Apart from taking a screenshot/movie and trying to save, and one know how I can reguarly just select the save device. (HDD)
