Thats why its called a "Challenge"
Was a challenge for me, I am an AR guy, and that was a grind at times. The SMGs just don't match my playstyle. I loved that I struggled at first and got very adept with them by the end. Now having fun leading lobbies with my pistols :-)
Try getting diamond on ar's and smg's and then stats being rolled back to i have NONE!
I nearly have diamond for the SMGs, but don't think I want to grind through the ARs.
If I even lost what I have now, I'd go absolutely ape5hit!
Yeah ii did it for snipers and working on SMG really kid diamond ain't hard you could get all Subs gold in like 3 or 4 days depends on how much you play everyday. sounds like a lot to do but realy it ain't i did all snipers in one day
SMG's and the Snipers are by far the easiest two lol. So far the Shotguns were the most annoying to get, the one-shot range of them are just horrible.
I found the assault rifles to be easy.. shotties were fine with the exception of the s12 and m1216 (take those two to hardcore for your 1 hit kills... same with the SVU)
I think far more people would have Diamond pistols if it wasn't for the Executioner. I see a few people running around with it and I think "You poor sod".
Also, getting the SVU gold in core was difficult. I has over 1000 kills before I decided to go into Hardcore and get the last 100 one hits
