One of the more recent, and absolutely COOLEST feature in FFXI were the new set of Weapon's and the pixy you traded, fought an NM, and added stat points.

Throw that concept out, that's not my point of what was cool, what was cool was my unique weapon, that had stats that to me was amazing especially since some stats were really uncommon and it made it that much sweeter when you were given the option.

I roughly understand this system and it sounds promising. Stuff like this opens doors for customization, when you own something unique, it's pretty great.
