Personally I hate this. Why not make all of the guns in each class identical statistically with different skins. The gun killed fast but was not spammable and news flash all of the guns on this game kill fast. I did die to it cqc from panic bursts a a few times but I also get knifed or blown up by a car here and there so not a big deal.
I had one class with it and used it some but never felt like it was the best gun in the game. Much more of a situational gun. I have also had to burst someone at range 3,4 even 5 times due to the vertical recoil even with a grip.
I did not see that many people using it TBH. MLG banned it which usually means a nerf was imminent.
