Accordingly, either the cheating is dealt with, I'll find and use an autoaim hack myself to level the playing field, or I just won't play. I have my doubts that the first one will come before one of the latter. I don't have the time or desire to record usernames and run video recording software with which to "submit a PM with evidence".
However, I feel that there is a brilliant and QUICK solution to this: after watching the kill cam, allow players to press a button (F3 or something, up to 10 seconds after the kill) if they suspect cheating. At first, YOU DON'T EVEN NEED TO DO ANYTHING ABOUT IT. Just allow me to feel like I'm not powerless in the situation, and give me a voice with which to say "BULLSH*T".
Now obviously, one suspected cheat shouldn't do much; nor should the suspected cheat count alone be used to punish a player. Nor should the total report count; heavy players will likely have a higher number than light players.
However, some ratio of 'suspected cheat kills' to 'kills' could be publicly part of their profile, and some servers could require a minimum to play on their servers; so cheaters COULD STILL PLAY; on cheat-allowing servers. Those of us that want to be on a level playing field could choose servers that require a specifically low ratio, and the world would be a much happier place.
It's not quite solving world hunger, but would make Crysis 3 MP more playable.
Please take this idea into consideration for the next patch.
