Guild Wars 2

So i recently logged onto my account and achieved 3,000 achievement points and to my horror i choose the wrong skin, i wanted the Radiant skin and instead i choose the hellfire skin, is there any way to reverse this choice?

You need to open a ticket with support. Top of page, left hand side “Support”.
Then top of page, right hand side, “Submit a request”.

If that doesn’t work out for you, at 12000 AP you will unlock the other skin.
