That's your assumption as you've posted numerous times on threads about this issue
In December when I chose my legacy name, the only information I received was in the in-game mail, which explained the name would affect all characters on the server. Bear in mind this information was available AFTER I chose so anyone who made the wrong choice due to not knowing it would affect all characters do have a right to ask for a reset or change due to lack of information. Not game breaking mind you but annoying enough to break immersion for some players.
Legacy is a great addition to the game. Implementing a name change will make those who chose, spelt or typed wrongly very happy, more immersed and intent on subscribing for a long time
