Just looking for a variance of opinions initially; I'm just past the Tower of Owen, so I only have the first set of jobs open.
More specifically, from what I've read online, the Knight job looks incredibly useless--it's basically a Warrior with more emphasis on defense, and only the Viking has the Provoke ability. With no hate system in the game, there doesn't seem to be any way to make mobs hit the Knight instead of whoever the hell they want, which eliminates the Knight's usefulness as a tank. How do you get mileage out of the job?
Is Samurai any good?
Do the jobs have any specific weapon proficiencies? I'm used to FFXI, so I'm accustomed to Warriors dual wielding axes because of a high axe proficiency--in FFIII, shouldn't I just equip the warrior with the highest damage weapons I can find, or is there any advantage to sticking with axes?
