RED MAGE and other jobs

[Madoka]

RDM could be a tank, but I don't see any reason for it to play like it did in XI. Traditionally RDM are jacks of all trades who dabble a bit in white magic, a bit in black magic and can melee a bit while never being terribly great at anything. XI took this and players managed to make a really awesome class out of it. However for XIV, I don't see any one class/job getting stats good enough to do everything. There's no point in a tank being able to heal itself if their heals are poor, or having attack magic if their int is poor. To be a GLD based tank means they will have high vit to begin with, and we all know how good PLD cures are. Unless the soul stone did something silly like give out +50 in stats, and you'd have to use melded gear of every main stat to be able to use everything

If anything Red mage would have to be a starting class and could have wizard as a job, if only to get a suitable stat spread and abilities that would work with their lowered stats across the board.

There's no point in a tank being able to heal itself if their heals are poor, or having attack magic if their int is poor.

Stats aren't remotely problematic given that the abilities themselves determine whether they use physical or magical attack power to determine their effects. It's entirely possible for a physical class to get a targeted heal that uses their own attack power and there are already "magical" attacks that use physical attack power (Flash and Circle of Scorn). Whether an ability uses physical or magical attack power is completely arbitrary. The only reason that PLD heals are terrible is because they're forced to use a heal that uses magic. If RDM were to be a DEX or STR class, you can be pretty sure that their "spells" would use attack power rather than magic power.

Unless the soul stone did something silly like give out +50 in stats

That wouldn't help at all, actually, since a vast majority of your attribute points come from gear. Because of this, no class is going to actually use more than 1 stat because there's no way to build up multiple stats to a functional point.
