You all know by now, my least favourite is the Black Mage for its appauling defense and inability to do damage that isn't quickly rendered obsolete by a Fighter's/Thief's/Red Mage's weapon or a Black Belt's fists (the latter costing a hell of a lot less). They're useful for one point in the game when they learn FIR2/Fira as field clearers, again when FIR3/Firaga comes along as an upgrade, then they suck after your melee classes surpass the damage once again, and once your Thief becomes a Ninja (granting it access to Haste, Temper and the mid-level field-clearers) you may as well not revive it next time it dies.
Pick an option, mash "VOTE" and explain away!
