Agreed, that way if one group dies, you'll have backup. Just make sure you have one person learn all healing and support magic(White and Green Magic. Perhaps some Time Magic as well), one person nuke(Black Magic), and one person with a long range weapon(Bows, Guns, Crossbows, etc.)so he/she can safely attack from the back. Give your healer and nuker mystic armor so their magic power and magic defense will increase. Also give your healer Rods so he/she can obtain extra MP and staves to your nuker as it also adds extra MP and powers up some elemental magic. As for your other 3 characters, give one of them a shield with either a sword, dagger, or axe and give him/her heavy armor as well so he/she can take hits and learn some white magic as well. The other two give them whatever weapon and armor you want, but I recommend giving one of them light armor so they can have more HP.
