It is neither an efficient use of my time, nor an appealing idea, for me (or, I suspect, hundreds of other Black Mages) to level up
three separate subjobs for maximum versatility. I barely have enough time to work on one, thank you.
Many people playing this game do not have the time nor the inclination to spend leveling so many subjobs to a level where they are useful as a subjob -- especially as their main job reaches successively higher levels. Thus, the answer to this thread is
not to simply say, "level them all", but to choose which one subjob solely provides the maximum benefit for a Black Mage.
At level 59, according to
a popular stat calculator, there is a total difference of 40 MP and 3 INT between a Tarutaru BLM/WHM and a Tarutaru BLM/SMN. Odd that even at such an advanced level, the
total stat gains from using Summoner as a subjob can be negated with a single pumpkin pie. True -- the summoner can use a pie, too, and they get Auto-Refresh and Blinkga. But at level 59, anyone who's put enough time into the game to level three subjobs could easily have saved up the gil for a Vermillion Cloak -- hell, I've nearly got the requisite cash, but since I play with a BRD regularly and don't have MP difficulties, I doubt I'll bother with the purchase. And that leaves a BLM/SMN with precisely one usable skill (Aerial Armor) that a BLM/WHM doesn't have.
Furthermore, most people leveling BLM as their main job are unlikely to have any other summons but Carbuncle in the first place until they hit level 65. And if that's the case, why should they spend all but ten levels with a mostly-worthless subjob?
By contrast, a WHM subjob brings to it reams of versatility benefits. At level 59, I can raise fallen teammates, cure almost as effectively as a WHM, remove most common character debuffs, and enhance the party's elemental defense. Not to mention that when I do get hit -- which is inevitable, not unlikely, no matter how good one's tank is -- a single Drain, coupled with automatic HP regeneration, means that the WHM doesn't need to bother curing me.
Using White Mage as a subjob also brings with it an increase in my enfeebling and enhancement skills, while Summoner increases neither. It gives me extra HP, VIT, MND, and defense -- all things that a Tarutaru can use more of.
As a BLM, I deal damage excellently: already, I fulfill my party's expectations of a consummate nuker. I can best serve my parties not by the occasional Blinkga cast and a few extra points of nuke damage, but by helping to cure the party and keeping their damage-dealing consistent.
Finally, I'm bloody sick of the argument that BLMs shouldn't be responsible for curing. It's a snobbish, elitist argument to a problem with a common-sense solution. We HAVE a curative spell: it's marked Drain. Furthermore, consider my 'normal' party:
Paladin :: White Mage :: Bard :: Thief :: Samurai :: Black Mage
Who's best to have a WHM sub?
-- The Paladin already has curative magic, but subbing WAR gives him better enmity management tools for his purpose in the party.
-- The White Mage obviously can't sub WHM.
-- The Bard doesn't have MP in the first place, and +CHR items aren't going to positively affect healing spells. (The Bard has to be mobile anyway, to keep the proper songs on the right people: this makes casting spells a bit difficult.)
-- Thief? Samurai? Don't make me laugh.
As someone whose main job already requires MP, BLM subbing WHM just makes sense.
