The problem is: Vanilla guns (inc VOG) were made almost too strong to begin with. This made newer weapons mediocre at best. We saw how powerful vex was, and it got hit hard with nerf but the legendaries have remained the same. The solution to stopping people using these is simple. Render them obsolete. Thats whats happening here. In a way its a good thing, it'll stop people using the same OP guns forever and waste bungies efforts when designing new weapons.
