FF never had Classes till 14, even then you'd be hard pressed to try and figure out who was what Job in FF7,8,9,10 and 12 as they tend to scrap the whole job system for more universal roles like the old FF14 Classes, you could use any skill on any class provided you learned it. still Pretty much all FF games had job identities in some form or another, some characters more defined than others.

while i dislike the armory system for many reasons the one that bugs me the most is the lack of player choice...if I'm a warrior i get to choose axe, axe or an axe as my primary weapon. what if i wanted to be a great sword Warrior? well i cant because the great sword belongs to PLD or some otherclass.

the other thing that bugs me is(recycling someones metaphore here) is that just because i got a gun @ lvl1 doesn't turn me into an automatic pro sharpshooter. in short i prefer XI's Weapon System and Armory System Versatility.
