This ABSOLUTELY nothing compared to the fact that people are reading and changing the data sent from the client to the server. At the moment (is like this from day 1 to now) you can basically change the number of gils you have whit whatever number, or change whatever item you have whit whichever you want. And yeah... lets not forget the teleport hack people are using to teleport to the last boss of istance and get free points in 2 minute...

SE MUST act, is not acceptable this level of hacking from a mmo whit subscription!
