The kill feed is like 95% Vandal headshots and pretty much every death I have if I actually manage to get face to face with someone is them insta flick bursting with the vandal and getting a headshot even if they miss the first shot or two.

I've only been using the Sheriff to learn but it's tedious. I don't know another fps game with such a high headshot % on the kill feed, especially one with such a low ttk.
