I'm a bit saddened that they aren't going to have a true Thief job in the game. I think their excuse that "No city would allow a thieve's guild to operate within its walls" is a poor excuse. I can understand that being a city of pirates, rogue kinda evolved from the thieves and pickpockets and can be used as stealthy scouts. But that's just the officially sanctioned guild. Since when does an underground organization like a Thieve's guild need the permission of the city to operate? If anything, they would probably have a guild/post in every major city and the powers that be may or may not even know of its existence. I think they tried too hard to make the class>job progression fit the mold that they started with for all the other classes.

Now, as far as races adapting to stealth based jobs, it would be pretty funny to see a Roe trying to be sneaky and hiding their huge frame behind a small Lalafel tank.
