Rarest titles in Arlor?

[Ardbeg]

I've always wondered how people got that title. I'm pretty sure it's the rarest. [The Midas Touch] is another rare one, although maybe not the rarest.

The title was granted for purchasing the tabard set during the first days of this game. If i remember right it also came with some stash slots. The attached APs were removed when the title became unavailable, but, yes, the title still exists.
