Actually guys I dunno... I'm pretty sure I remember reading that Thief was going to get some kind of smoke bomb emote.

Planned for further down the line is the addition of job-specific emotes. The finer points of how these new motions will be acquired are still under consideration, but players can expect a charming set of animations that will allow them to role-play their chosen profession with greater expressiveness than ever before!

Underlined bits: Now I may just be reading this wrong, but it appears to me like there are going to be more than just one emote per job. The picture on the site beside the text shows a Warrior with his arm extended performing some sort of "come and get me if you dare" gesture with his hand. It also appears as if we're going to have to unlock them, possibly for each individual job. Hopefully it's a fun, story-driven quest rather than a long, tedious quest.
