If it is true I want them to go back and use 5 characters again.
Black Mage-Magic Attacking
White Mage-Magic Healing
Finesse Character-Stealing, Jumping, Dexterity Fighting, Magic for its Ranger/Rogue type of fighting etc
Tank Character-Good old bashing of the character, combo related moves, combos you can already choose, Magic to simply upgrade the weapon, etc
Main Character-Good use of physical and magical fighting and technique. Cecil and Beatrix were perfect examples and maybe FFVII's character since you can customize them basically.
