Yes, it's B- for elemental magic.
The job sounds interesting and I will probably level it because I love all things magey, but . . . I'm even more worried for SCH and RDM. It's another job that can nuke, enfeeble and buff and has some job traits/abilities to make their spells pretty potent. Slap on /RDM or /WHM on it and it can heal too. I'm curious to see how powerful these -ra spells will be as well.
I know it's early and we don't have a lot of info but I am a bit concerned.
I'm not to worried about SCH since it will still have it healing and embrava and is fine in the nuking department. RDM on the other hand looks deader than it already was. I will definitely be leveling GEO though, it looks really fun.
In regards to RDM, it's partially why I've been wary of the Mystic Knight concept, earlier note to the community's aversion to hybrid classes aside. Assuming they get T2 Enspells, they'll be inheriting the same garbage RDM has with them with no promise of T3s or higher being any better. On the other end with DRK, you can have a sort of MK-Lite via using a GS and Endark, and I'd probably call Endark somewhere between a T2.5 and T3 Enspell as is. If MK can further cast nukes up to, say, T3, then yes it's another lol toward DRK and just more homogeny with RDM.
With a fresh approach, I have no doubt it could be made to work, but its past incarnations aren't terribly inspiring with XI's current mechanics. As someone who's long since wanted RDM melee to be bumped up in viability, this also a mixed excuse for SE to not bother and then the community to go, "You wanna use pimped Enspells? Play Mystic Knight!" The pending enfeebling adjustments have been a development limbo for so long now that they're joining the likes of Duke Nukem Forever when thinking of vaporware. And even then, if SE really wanted to pimp RDM as an enfeebling class, it needs a lot more spells to flesh out that niche. Geomancer also bringing enfeebling potential is kind of a monkey wrench there, too, even though it isn't conceptually unheard of.
I still mourn for RDM's current situation. And if I had to guess, MK would also poach spells like Temper and maybe the Gain line from them, too. In the end, this could be one of those situations where people think, "Why couldn't these JAs/Spells have been given to other jobs?!" sort of like how SCH and LA/DA panned out prior to more recent adjustments.
