So what FF Characters do you think don't get enough appreciation? (From a character perspective, not a usefulness perspective)
Minwu definitely comes to mind. His devotion to the rebellion, his mysterious yet noble looking get-up, his sage like wisdom, and his sacrificial personality (especially with his SoR line "We chose to die. But we did so that others may live.") really should earn him more fans than he currently has.
Cecil also comes to mind, seeing how he gave up everything (his home, his rank, his lifestyle) to do the right thing. His quest for redemption and the forgiveness that he struggles to give to Golbez really made him an involving and dynamic character.
