it can also cause errors temporarily if your personal connection is off by a half milisecond with that of the servers output/input. Strange things like that for personal servers. however, if we had a massive type server like they use for games such as WoW, LotR, and GW... then things like botting lock ups, map over flows, and lag to the 999 Ping extent, wouldn't exist. Only problem is, to rent a server like that would cost several hundred dollars a month.
