Re: peace keeper ...

PK is getting nerfed soon based on the recent patch notes. Not sure how, but something is happening.

PK can't one shot anyone with 175-200 HP anymore though thanks to the headshot nerf. I think you most likely got two tapped or was hurt by someone else before the PK shot you. There's also a chance that two people shot you at the same time with PKs.

I don't know but it best to check the damage review carefully or save a clip/video. 

But PK is getting addressed. 

Shotguns (including the mighty Peacekeeper) just got some adjustments in the server patch that went live yesterday. Check out the details when you can and let us know what you think of these changes.
