people want to lose the surname?
everyone already knows if they made it first name only there would be a crybaby post of why they had to change the name of there character and the ones who want to drop the surname will be the ones to post there mad about it.

I think the naming system is fine. Changing it will just create problems like when people got server merged/world transferred in FF11 and had to end up changing their name.
yup, and this time the all the "worlds" will be one big world
