I sure hope it isn't. When I bought it I was under the impression that it was something that would be removed forever and only the earliest players who bought it would have it.
They said it wouldn't be removed forever at the time. I want rare/unique stuff too, but at the time my server had about 40 people and you couldn't make money apart from dailies ... I was only able to afford the cheapest white one, so I appreciate the chance to get a couple better ones.
