I think it would be great if the teleport spell (or even, another, similar spell) could transport people to Ataraxia's Haven.
It's a great place to sell excess items, so I tend to travel there quite often. After a bunch of my stuff doesn't sell on the AH, the mailbox right next to the vendor is incredibly convenient. Since they take all types of items for resale, it's a great place for selling a massive amount of junk at one time.
Now, don't get me wrong. I realize that it's just a hop, skip, and a jump to go from an airship to Deneith, and then have Evil Joss Whedon send me to Ataraxia's Haven - or a similar trip via House K and their port agent. It's just that there is already a teleport spell. It already sends us to convenient places. Might as well add another one?
