Thief
Human, Moogle

For the best basic jobset would definately have to be the Thief. What makes the Thief class so unique and special is the different thievery skills that the Thief has. The 'Steal' skills allow the thief anything from the enemy units, inculding the JPm EXP and Ability! In addition, this is the first class that we see has a useful Reaction command, 'Counter' is a useful basic ability in it's class, despite the fact that there are greater Counterattack type abilities that are available.
