I submitted a ticket over the weekend to have my userid changed, and today they made the requested the change. In the ticket, I said, I purchased the digital Imperial Edition with userid Kale9562. Can I request a one-time reset of my userid? I did not realize it would be the name used in chat channels such as guild chat, and the numbers in my name break the fantasy atmosphere.
I was surprised that they were so helpful on the first request. If you have a username that you are not happy with, you don't have to be stuck with it for all your TESO days. You can still request a change while it is still early. This friendly policy might not continue after the game has been out for a while.
