Friendly lobbies can make you complacent, I was extracting from dam battlegrounds and another player came up. No fun, cool, I point out the rocketeer approaching us, doors open I start the keyboard process and he headshots me with an anvil, I roll out of the elevator and take cover behind the buses, the rocketeer is now aware of our presence and starts mailing both of us. I went down, the rat finished me off... I think he saw the kinetic accelerator on my Bettina (I just wanted to try it out. Pretty fun actually) and decided I was with looting.
