I have a question about some of the perks that I don't fully understand and that I haven't been able to find an answer to by searching...
Fast Hands; I know it makes you faster at swapping magazines, but does it also make you faster at aiming?
Flak Jacket; Does this only make you take less explosive damage or does it also reduce bullet damage like a real Flak Jacket?
Hardline; Does this only earn points for scorestreaks faster or are you earning regular XP faster in the process?
This one isn't a Perk but on the FMJ bullets;
Do the FMJ bullets only penetrate through walls and damage enemy equipment faster or do they also do more damage to the enemy themselves as well and/or kill them faster?
