One of the main problem this game has is undoubtely hackers, with aimbots specifically. There are way to many web pages selling specific hacks for this game and I'm pretty sure Battle Eye know that. I know this is not the place to report hackers or cheaters but you may consider adding a public internal killfeed so AT LEAST when we are killed by cheaters we have a tool to identify and properly report them. It does not have to appear in the game screen, it could be registered in the main menu when you are leaving the game or something so the inmersion don't get lost.
Modders get it done so I guess it should not be that hard to implement.
