So doesn't say that name changes are permanent and I changed mine thinking it was a temporary thing for clan raid and no one mentioned that it was permanent and there's nothing there that indicates unless you dig really deep down that says it cannot be changed again. I just want my old name back and for you to include an "are you sure" confirmation message cause it's really messed up that there isn't any clear indicators.
EDIT: So banned for this. Didn't expect that hard of a reaction without a word from Bungie. It wasn't clear that it was permanent when attempting to make the change on mobile.
