Let's keep it on topic, boys.
Lizard Dude, I think you're probably right about the Master. Though I have not leveled a Master to maximum level, I would imagine that you would see an insane number of hits with equally mind boggling damage. I'm not sure if I'd say the class is the best, however, as it starts out extremely slow during the beginning of the game. Low defense and rather low attack (when compared to that of a Fighter) makes the Blk Belt pretty useless for a nice portion of the game. End-game, definitely a force to be reckoned with, but early on I've never had good experiences.
Some people swear by the job though. Whatever works, I suppose.
