There's a lot of boosters in that "elite group", but truthfully its not that hard, you just have to choose to do it, cause you'll eventually get kills no matter how bad you are, and 5 kill streak isn't elite.
But anyways! Back to the point, I have the gold assault shield, wasn't hard but god I hated wasting good games just to get it gold, so I'm not going for diamond, but its not like I CAN'T get it.
Spoken like someone who hasn't done it. Come back when you have legitimately completed the Diamond Specials challenge .
So how many crossbow bloodthirsties do you have again?
And to throw the Boosters card down actually reinforces the OP's point. If people are prepared to cheat and boost for the challenge, then it must be "that hard".
You won't see another Diamond Shield because they look nasty, and you can see them from outer space which is the opposite to camo when you think about it.
I have never once put the Diamond on my shield. I only did the challenge for the Ballistic Knives because they look really nice, the Crossbow looks pretty sweet too, but again a bit of a position giver when it's on your back.
Don't listen to all the idiots griefing you, especially the one's who haven't even done the challenge.
My assault shield stats are 139 kills, 0.41 K.D.
As I said you don't need to be great to get it gold, any average joe can do it, it's just about sticking to it. Getting the 2 offensive weapons gold will be alot easier since its easier to kill and usually 1 hit kills. So the shield is the hardest part.
