13.5.1 Accuracy

Accuracy in Group Combat (PvP)
When fighting other players, a player becomes harder to hit as more players attack a that target. That is to say, if only 1 or 2 players are attacking a target, then they will have perfect accuracy (discounting any other bonuses or maluses to accuracy). However, as more players try to simultaneously attack that target, the din and chaos of battle make it increasingly more difficult to find an opening through which to cleanly attack that person. In practice, this means attacks are more likely to miss.

Therefore, in group combat it is best to divide up targets to ensure optimal accuracy of all attacks.

This effect does not occur for PvE combat.
