How to change username?

Unknown

Hi, all.
Does anyone know how to change the username on the PVP events? Kind of regret my current choice. Thanks

When I got my account linked between the PC and Mobile versions (yay beta!) I asked for it, and the support reply was that changing usernames isn't possible right now. They expect to add the feature in the future, but right now, no dice.

Thanks. Sigh.
