Ping is what is generally understod to be the time it takes for information to travel between your computer and the server you are playing WAR on. Ping is measured in milliseconds. For example, a player with a ping of 500 will seem to have a greater reaction time between activating a spell and it being performed, than a player with a ping of 150. Thus, having a high ping is detrimental to a player - particularly those playing a melee career, and may put them at a disadvantage compared to players with lower pings.
