so a gun where you get traded because you're unable to shoot, and requires a rifle on the site with you, and isn't good close up, and can't multifrag a rush is op? I think you should rethink how it's OP. It's an expensive weapon with niche use for picks at the start of a round or for retards that walk into a site one-by-one with nobody to trade. The only nerf that wouldn't care about is a change in the magazine size, but even then something should be compensated. The AWP is fine how it is, if anything the most recent 'bugfix' was unnecessary. People using the excuse that the best player in the world has been an AWPer 2 times in a row now, never cried when it was a rifler 5 times in a row. Teams don't use more than 2 AWPs GENERALLY (D2 mid doors last round but even then they pick up an AK after they spam, or HAVU) because it isn't the best weapon in the game in the vast majority of situations.
It's a niche weapon that's very good at it's niche, and somewhat worse at everything else, like it should be.
EDIT: The SG is overpowered, it's the best weapon in almost every situation. The deagle is retarded, it should have way better 1st shot accuracy, but shouldn't be able to 2 shot armoured opponents at any range, it shouldn't be used as a pocket shotgun that can also be used at mid range.
