Just yesterday, a guy killed me like six times in a row without dying on Gauntlet. In face-to-face shootouts at 15 meters, he wasn't even playing Recon, but every time I moved on him, bam, he would turn around as soon as I came into the room. I was dead before I even had a millisecond to take aim.
It was so obvious: complete superhuman behavior. There were no motion sensors around, and I was crouching and walking most of the time to avoid any noise. Yet, as soon as I got in a room with him, he made a perfect 180 or 165-degree turn and whacked me in the head in milliseconds. I mean so quick you wouldn't even take a third of a breath.
It is ridiculous, and this leaves a real sour taste in your mouth. Since you, EA, are not doing anything that proves effective other than banning free amateur hacks 90% of the time and some less sophisticated paid hacks, the player is left with two options: either leave, join the hackers, or accept that every game is going to be like a cup of black coffee with no sugar.
