Hi - I’m just looking to see if anyone has an answer for this issue I’ve encountered. There’s two different names on Tichondrius I have tried to get use for a character I’m intending to level and have as an alt, and both show the green checkmark when in character creation. Hit finish, pick starting zone, and it tells me the name is unavailable because it’s taken by a player.
Is this…a bug, and it should be showing the red X in creation? Or does this mean that the character is on an inactive account but not available until next expansion? If anyone could offer some assistance that would be swell!
Are the characters night elves by chance?
The ones I was trying to make? No - I mostly play horde lol. And I’ve searched the character on armory and tried to add in-game, both ally and horde, and nothing comes up 
What are the names? If I am not mistaken the green check only indicates that the name is not currently taken by another player. It doesn’t indicate if a name is blocked because it’s on the list of names that Blizz deems unusable. Trying to use a blocked name will give you the same message as one that is already being used.
Like if you are trying to name a character Queenie. No one else will have that name so it gets a green check, but it won’t let you use it because using titles like Queen is against the rules. When you try though you get the same that name is taken message because they simply can’t be bothered to program a different message for blocked names.
That’s what I thought at first too - but the two names are, on an armory search, nearly maxed out with people having named their characters them. And on other servers, I get the red X when I try to use them. I actually previously got the X with one of them, as recently as like a week ago, so all this kind of makes me hesitant to say them in case someone sees this and swoops in to troll LOL
This could be your problem?
