I would review the FTP limitaion menu here . I think FTP are restricted from having a Legacy. In a nut shell, Legacy is your last name for characters server wide, it gives you options to; species unlocks, character unlocks (both per character and legacy wide), as well as some quality of life upgrades.
EDIT: I forgot to mention that the legacy xp is shared with all characters in that legacy. You gain legacy levels which give you access to more unlocks. A percentage of xp you gain from missions, killing mobs, etc is put toward your legacy level.
