I know the transfer is to stop people from jumping server to server making massive amounts of gil, used to see people buy tons of low stuff leave server, then they would be back right after. Some of the others are supposed to stop rmt, we know it doesn't really do anything. Also some of the wait times on certain things are due to an outdated data server, the one they use to constantly keep our items the way they are no matter what, you crash look items still there, your not rubber banded backwards ether. Fc thing was originally to stop people from selling fc's every other day, but people still sell capped fcs and wait the day so that doesn't work ether.
