I have requested a Funcom ID change in this thread:
forums(dot)funcom(dot)com/t/change-a-funcomid/186899
As stated by a Funcom employee, I went to their Zendesk support page and had to create a bug report, because there was no option for a Funcom ID change request.
I got a confirmation E-Mail that the ticket got created and since then there was no feedback from Funcom.
So I am asking again:
Where or even is it possible to change your Funcom ID?
As a suggestion: A player should be able to change their Funcom ID on their own. Maybe only once per year, like in GTA V with your account name.
Because I have seen a lot of people with their real names as Funcom ID and also some less pleasant ones. I am pretty sure these people would like to change that as well.
