Unless you have been living under a rock for the past 10 years im pretty sure everyone knows what the difference between lag compensation is. Considering it was in games as far back as Call of Duty 2. The reason you notice its disadvatages so much more (ex. dying around a corner) is because you move 2 or 3 times faster in gunz than a standard fps plus the fact that you have players with pings many times higher than you do in a highly populated game with regional matching. Everyone always used to bitch about people with 100+ ping even before antilead. Use the room tags if you want to lead.
