Why even have a picture of the signs when they don't connect to lore anyways. Just have a picture of the 3 seals we are fishing for instead of the 6 signs. That way it is more simple, easy, homogenized, and intuitive. That way it's easier to level to 80 and finally switch class.
And if they are going that route anyways just delete the AST class itself, no one's playing it for dungeons or endgame anyways.
