And then we have what is apparently a first, the instance quest being on main questline not on a branch. And, since the instance on easy is bugged at 3rd, and shows no sign of emergency patch fixing it any time soon, I don't think anyone completed the questline yet.
This is the bit that scares me. When the next content update comes out (most likely with a new continent) the quest to go there will probably be tied to the current questline.
A lot of players are not going to be done with the instance quest quite so soon and will end up locked out of the new zones.

It needs to be handled like the move to Thunderhoof Hills where the quest to go there just pops up at a specific level.
Also, there needs to be someone there to port you back and forth because Snoop isn't supposed to be able to transport you to new continents!
