I'll answer this one op
Lady Vix i agree with you and op but there is a way to have the cake and eat it as well.
A name purge to happen once a year to all non subbed accounts at the time with an automatic email one week before hand.
that is to notify all of this process and to log in to your account to save your names if you are currently Unsubscribed.
What do you think?
To lose your names you would have to be Unsubscribed at the date and time each year and miss out on the notification in your email.
Maybe add an option in cartel market for 500 cartel coins you can permanently save your name to that character only affected with a name change that would then save that new name instead of the old one.
