I'm not bothered by the lack of Dancer being added simply because:

- I'm excited for both RDM and SAM
- Much like Rouge and Ninja were name dropped heavily before being added, RDM and SAM were as well
- The hints were there. They were always there.
- There was a tweet that was corrected when they announced RDM as "one of two new jobs for Stormblood." The "two" was removed.
- There's nothing saying we absolutely won't ever get Dancer.
