considering the most popular/requested jobs were;
THF, SAM (only really asked for in the west really), and RDM (mainly asked for by the JP)
With THF being the most asked for, we got ROG/NIN.
They said "Caster DPS" was the 2nd most asked for, but we never got that, other than MCH/BRD. (Musketeer being 5th in line, but barely asked for)
And SAM was replaced by DRK, and AST replaced Time Mage, which replaced RDM.

So just because people ask for it like crazy, doesnt mean we'll get it.

(Similar to how Yoshi asked what race, and everyone wanted a mammalian demi human, like viera, and Yoshi wanted straight up inhuman lizard people. Well, he settled on semi lizard people, because its what he wanted.)
