As a Catlike Thief i've been waiting for a thief class since i preordered the game in 2010.

Plus it's not a FF game without steal/mug abilities. A thief or stealth based combat class woud be so awesome to play, or if it included treasure hunting abilities that help a party out with drops or farming. Some burst thief abilities are pretty powerful but in general, stealth based DDs arnt as powerful as other counterparts in MMOs, but still would be extremly fun to play.
