I'm not saying purchasing something with actual currency should give you buffs.
Skins shouldn't determine what stats the weapon has. That's not what I meant, but you all took it that way. Like damn if it was a different game other that you didn't like, you'd have the same opinion but since we're all riding the bandwagon of "CSGO IS THE BEST GODDAMN FPS EVER CREATED", you need to try your best to defend it lol.
But what would be nice, is something like weapon progression. Say you're using the AUG, you get 50 kills and you unlock the scope for it.
