So we have bottles of Fantasia to enable a player to change their appearance, race, gender, etc. Problem is, it doesn't seem to enable a name change. I understand one reason for not allowing this is to curtail a possible avenue of further character theft by hackers and RMT - you know, change the character's appearance and name, suddenly the old character doesn't exist and will be harder to give back to the owner...

I digress. I know some people who have done the complete appearance change, but they don't like having to keep their old name since it doesn't fit the new character design, and they'd like to have a name which is lore-appropriate for the new model.

Don't change how Fantasia works but, instead, consider the addition of Namingway cards. It's an item which fits the classic FF lore, giving a nod to previous titles, and fulfills the function of enabling a person to change their name. Make it a rare/unique item like the Fantasia potions. Maybe a future veteran reward, or event-related item?
