I saw one of the discord moderators talking about this, he said that when the game launches everyone will get a rename token, whoever has an honorable account will get 6 rename tokens.
It looks like they will give everyone 1 token because some people put the wrong wartags.
Thank you, this is my case, I had no Wartag so I was trying to put one and receiving the error, so I tried another one just to see what happened but now I cannot change itš¤£
