(adsbygoogle = window.adsbygoogle || []).push({}); So pro perks i know alot of guys are not doing them just leveling up.

Anyway

Flak jacket - last challenge is quite a fun one. It Trey version of hot potato just with nades.

Throw 5 nades back......
Ah this one annoying because most people cook them. And most people use the sticky.

Hardened - Destory a piece of equipment YAY easy.
Eh no it pure luck and finding something to destroy which you can destroy, with you behind a wall.
If only people would put there claymore near me when am camping :p.

Second Chance - This one just annoying because most people will kill you before you fire a shot.

That my top 3 most annoying pro perks to collect.
So what at the top of your list

Yeh hardline is pissing me off. I get stuff like Black birds and leave em there my team just run straight out pissing me off lOl.

It took me less than 2 hours to get this is how i got it... I walked with C4 on my hand and threw it when i saw an enemy and when i had 2 kill people in the radius of my jammer or motion sensor i just walked near the enemy planted it and killed them right away

ghost pro by far is definately the hardest..
