@xSagez Well no. Unless I'm missing something the R-99 was a moderate risk high reward weapon at close range before the nerf. It could also drop targets at range effectively on PC. The only downsides were that it burned through ammo and needed an extended mag to be used freely.
It was easy to use, consistent and better than most other weapons outside of a few situations. I'm not in favor of a nerf but lets not lie and say it was balanced when most of the other weapons were ignored in favor of it.
Well until disruptor rounds gave players a few more options but I don't think you want them back.
