I think the idea of having chars with the same name is good, but we would have to have a thing in chat that maybe you can click a name & then it will show you the username, this would be good for ignore, lets say someone just wants to bother you for the fun of it, you hit ignore & they login to another char & start it up again. With this way you can just ignore the user name & all chars included with it, It probably will be treated as something of a last name for chars maybe?
& maybe a way to leagaly change a first name in-game (if you doen\'t like to many people with your first name)
