My characters are pretty much the same as well as your guys
Lenox-Warrior type, mainly trained for the melee fighting and does the most damage, sword and shield type
Malena-Archer type, mainly range and a little polearm
Zenra-Priest type, also makes potions and is the healer of the group
Jarinex-Mage type, pretty much the damage dealer after he gives haste to Lenox and Malena
