Which one of these classes should I not have?

Ive been playing final fantasy 3 ds lately and i was wondering if i chose a bad class my characters are warrior lvl10 black mage lvl13 red mage lvl9 white mage lvl 12

I think that's a good mix, although I had a ninja I think that is a good mix0black mage for power, white for healing...Wait-ditch the red mage.Red mages just have a mix of the white and black mages move set's, I'd suggest maybe a ninja or another physical attack group like a dragoon.(Should have 2 of each group-2 magic and 2 physical)

Dragoon is good.
Try it. ;D
