So there is currently at the time of this post talk in the Dark Zone West of people using a process called Lagswitch. From what I am understanding people are using VPN's or equivilent and when there being attacked they imideatly switch VPN servers which causes lag with Divistion 2 and gives the player doing it a temp GOD mode where they cant be killed or anything and provides stat stacking as well. its a MAJOR exploit being used in the Dark Zone aparently.
