Transferring from Legacy Worlds

[Shirai]

Think that will stop a lot of people.

Or transfer with items that have a guaranteed value which you can hand in for gil quickly.
On my server one person was buying Allagan Bronze, Silver and Goldpieces for a little over their NPC value so that they could transfer with most of their fortune intact.

If you are transfering with multiple millions a couple 10k loss should be negligible and it's easier than figuring out which items are of equal or better value on the markets.
Apart from that, the market is too unreliable for a strategy like this at the moment.
