There are people who think of FF as anything past FFVII, and there are people who think those are crap. There are people who worship the ground Hironobu Sakaguchi walks on and there are those that are glad SE got rid of him. There are those that think Tactics doesn't count as an entry in the series, and there are sane, rational people.

Arguing about what makes Final Fantasy "Final Fantasy" is a tired and pointless argument precisely because of the previous, so trying to dictate what is "traditional", and therefore what should make it in the game for that specific reason is a farce. A more grievous offense is speaking for an entire group of people as some kind of authority. The very fact that there are people who would love to see that job(and Geomancer, Beastmaster, Sorcerer, and even Mime) should be enough evidence that there's a demand for it, and that you can't or won't see that is your own special brand of myopia.
