I have an email adress from my GW1 account that now is invalid I wanted to change that in the past so I changed my GW1 email to the new one, although I had to keep the username from my old email adress because it is linked to my ncsoft account. now when i linked my guild wars 2 it now uses the old email adress since it is the username from my GW1, now I can’t change my email adress.
