Black Mage is utterly fine. We got the fix we needed in 4.05, and we're constantly fighting with Monk for second best DPS.

And you know what? We don't need utility. We don't need gimmicks. We're a goshdarned self sustained man sized artillery, and most groups either take a Samurai or a Black Mage or both before considering utility. Why? Utility is nothing without stopping power, which we bring in droves. If anything, the only change we'd need is Fire IV being 280 base potency again, but that may be much. Umbral Hearts are utterly fantastic, especially since they allow us to hit objectively higher numbers than in HW, minus 20 base potency be damned because we get more Fire IVs per Astral Fire rotation.

It's also hilarious to see people complaining about this lack of utility in Black Mage, especially since in Heavensward, Bards complained about being there for the support and no damage.
