Exactly, it is obviously not correct to nerf all these guns, if you paid for something that worked "normally" (or atleast how you wanted it to work from the begining) and then it turns into something worst, you simply wasted all your money and it shows how bad is the staff team taking desicions before releasing stuff.
Just imagine you buy a new phone, and the company that made it releases a update to totally change the way it used to be, and it is now a piece of sh*t. Would you be pissed?
