they have already stated some time ago that they were going to add the option to change your character name. it's just a matter of time.

also i only read a few pages. but another good use for name changing is when people use names like i got. when you use a non-original name like something from a TV show or anime. your character appearance customization options are limited. you always want to theme your character after the TV character.

not that i would ever want to change my characters name
