Fusion rifles are only a one shot kill if you hit with all five rounds per burst. So it's not a one shot kill. Unless you hit every time witch Doesn't happen. No one hits every shot with a fusion rifle all the time. Stop being a noob and calling for nerfs when you don't understand how the weapon works. The pocket infinity got nerfed because it was op in pvp. Cutting the magazine size was a great way to balance the weapon. Stop crying and start playing. Or just stop playing the game all together.
