I think the one that set things that set blue mages off for me is the sheer difficulty to get there skills. The beast master and the morpher are the same way. I like my classes simple. Paladin and Mog knight for sheer strenght. A summoner and regular mage for healing and ranged offense. A white monk for both. And some random guy who fits my fancy at the time ( or law). This startegy helped me beat the final boss and I think that the only reason I really would stare at a Blue Mage with goggling eyes is their pesky Damge to MP r-ability
