I play SnD a bit and IW/3arc loves ripping us off, especially by how we only get 100 weapon XP per kill. Anyways, mine and my friend's weapons have been leveling up abnormally fast. I am on quadruple XP and I am a low level 30, yet my ACR is already level 16-17? That doesn't really make sense. If I played TDM maybe I'd believe it, but I don't.
