I seem to be in the minority, here... While I loved Tactics (And generally disliked all other Final Fantasy Tactics games after the first one...) I really don't want to see Chemist as a job. For starters, it was a really really basic job in the game. Far from "An iconic Final Fantasy Job from the classic games".

So far we've got a bunch of super-stars: Paladin, Dark Knight, Ninja, White/Black Mage, Summoner, Dragoon, Monk, Warrior
And a couple of B-Listers: Bard, Scholar

And you all seem to want to add the Corey Feldman of the Final Fantasy universe to the game. It'll be a sad day if this comes to fruition!
