Also, when you're playing Call of Duty or something of the sort, you don't think "Man, I wish sync was bad so I couldn't shoot the player directly."
And people go all crazy when hitboxes are fucked up, so seriously, you cannot prefer bad sync over an accurate hit system.
EDIT: Holy shit. This could be used to put an end to db on foot. It can be used to determine whether the player who dealt damage was in a vehicle, and prevent the damage from being translated to the player. It could be used to end deathmatching as a whole (if you wanted to go crazy about it). You could determine whether the player who shot was raped, robbed, kidnapped, etc in the time limit, if he was not, the other player simply does not take any damage. Same with cops, if the player is white/yellow, no damage is taken.
