What's the best combat setups?
To each their own. Personally I usually do 1 tank, 1 big melee dps, 1 rogue (front row)
then in the back, i do 1 healer, 1 mage, and 1 archer
My playthroughs are usually quite similar when it comes to combat characters
My archer i use Aire, rogue i use Cali, and Mage i use Jean
My character is usually the healer and i typically go with Seraph as the race, while my tank/melee dps is usually an Orc for the class Berserker. That class allows you to attack again if you kill something once per turn.
I know several people use Necromancer on one class and just solo combat scenarios.
