Diamond camo unlocks for the weapon class once you obtain gold camo for every weapon in that class . For example: By unlocking gold camo for every weapon in the assualt class, you'll unlock diamond camo for every weapon in the assualt class.

Only if it negativetly impacts the gameplay of others. Reason why it was such a problem in MW2 was because you could get a killsteak that literally ended the match. I mean what can you really boost for in post-MW2 games? Tags, emblems and camos. You could try and get high level kill streaks, but once you get competant enough (and aim assist is reblacned) everyone has their fair shot at it if they grind.

Also if you're trying to boost your stats, matchmaking will just put you in a higher rank in which you will be whooly outmatched since those players earned their K/D or PPM.

I am amused that Treyarch included a booster report button when there's not much you can do that really matters to the overall game or doesn't actually end up hurting you in the long run.

Yes because when I see someone with a diamond sniper rifle, the first thing that comes to my mind is my game is ruined! Although it is, since they're just a quick scoping mongrel who abuses auto aim. But that's the same for any person with a CPU + slicencer sniper these days.

But in all seriousness, only a weak willed fool would let someone who's running around with a diamond camo affect their gameplay.

Are you that dense? Who cares about the camo. It is the manner in which it is obtained. Boosting in any form is cheating. Anyone who would boost for something as stupid as camo will do it for other reasons as well ie for kill streaks and the like which does effect other people's gameplay. Also if they are in a match and spend that whole match boosting what happened to their team mates and does that not effect other people's gameplay?

If you're willing to plan, coordinate and take the risk to boost, that person earned their camo just like some nut who gets it the normal way. Considering you can't do it in free for all, it takes a lot more effort to properly boost. It's the failure of the teammates in not detecting the boosters.

My personal favorites are the Carbon fiber, Art of war and blue skulls have bit better blue than the tiger camo.

I never really cared about the camos, they're not important to me, I'm not probably going to play this game for too long anymore anyway, the constant TDM matches just make me so bored, Domination isn't that fun when you go solo and FFA seems to have always some try hards.

I've gotten a chance to play 3 multi team matches, I kinda liked them, they're more strategic than regular TDM.

Got to play one SnD match against one of the clans I've hated since BO Wii, GG7, guess they have hard time owning the enemy teams now

Diamond camo did look kinda cool on one sniper rifle I picked, but it's not a reason for me to no life every single weapon in class, I use those what I like to use, I test others by going on guerilla warfare
