Ninja, do we need it?

[Abriael]

Ninjas have never been tanks in Final Fantasy, they have been in XI only because of a combination of development oversight and user exploiting.
So to the ones saying "this isn't an history lesson" (which is quite a bit laughable, since the only tanks in history came quite a bit later than ninjas, are made primarily of steel and carry a turret with a cannon), I can easily respond "No, it's a Final Fantasy game", and Final Fantasy ninjas aren't tanks.

Besides, we already have plenty classes with tanking potential and tanking-related skills (Gladiator, Marauder, Pugilist). Didn't we want unique classes? because having everyone and his mother perfectly able to play tank isn't exactly something that encourages uniqueness or characterization.
