it takes 2 shot while ADS from 10ft away to kill some1 now.... FML.. here comes the SMG takeover!
They did the nerf a couple of months ago... I used it for the first time properly about 4 days ago and got it gold easily after a few hours. I got the occasional WTF moment or 2, but for the most part it's savage.
I'm not sure where you have been ,but it seems to me that the 870 almost has the range of the KSG now. You don't need to aim with it at all, even if you don't have a laser sight. And even if you miss your first shot ,the thing pumps so quickly that it doesn't matter.
