i prefer white mages, since im more of a defensive person. (plus, later on, they can usually get holy in most ffs.)
although black magic can get pretty nasty sometimes...(thinks of flare, meteor, doomsday, ultima, etc.)
then again, in some games, haste is white magic...that seals the deal. white magic it is
oh yeah! in ffV, krile's white mage costume looks like a kitty! a kitty! definitely white mages.
