Hello!
Yes, I remember this guy. I fought him several times. Each time he showed little or no lag, except for when I knocked him down. As soon as I made that second shot with stubby to kill him, he would lag, then slide to another position. This ONLY happened when I knocked him down, not when we were fighting, which in my experience is usually an indication that the player used F8 to evade death. Obviously I don't have any screenshots proving that he did this, but I believe pask and Milko were both present (pask was actually standing right next to me when he did it). For the record, I'm not "angry" with this person, and I wouldn't let it affect my judgment if I was. I've never even seen him before.
