my first team was exactly the same as Zerv's.

you cant go wrong with it.

on a second playthrough i used a red mage, monk, white mage and black mage. it works well but could use more physical power. its also expensive because of magic but you have a very powerufl fighter, someone who is good at everything and dont miss out on any of the powerful spells.

fighter
monk
fighter
white mage

or something along those lines will give you loads of power and great healing which is all you need but it could be a bit boring and having two of the same job class is unsightly.
