Yeah what really bugs me about the anti-cheat stuff is that they claimed they were going to finally fix it in that last big patch by updating the netcode. Never happened, all of the cheats still function and continue to be more widespread. People have also gotten clever about not being obvious with them, there was a video on youtube a few weeks ago of some guy using a multi-hack that lets you see when other players are targeting you. He went onto a 64p server and found something like 10 people kept continually targeting him from across the map, not accidental mind you, actively following him without any line of sight.
I can still do well despite the cheaters but it would be nice if they gave the slightest shit about stopping that stuff.
