I remember as a support on Lazerazor, I was hacking my firebase when an assassin popped in. She started to shuriken me and as soon as I got hit, BAM controls locked. The game wouldn't let me move or stop hacking and as a result I died from a gold crit assassin. During that same match I hacked a rocket turret. I started to move when my controls were locked AGAIN. I could move but could not look around. So I jumped off the ring, making my total game 38-11-2. I've heard of bullet lag but never the lag which locked your controls. Bullshit.
The one time I was in a PP lobby it lagged so badly the turret hacking bar would reset 3-4 times before you finished.
