It's time to break up and begin anew.

Honestly, now that they've show they're willing to give Jobs the Mastery traits to split spells, I don't think they really need to be separated. It would be fairly easy to use things like Corruption Mastery and Broil Mastery to just phase out the Arcanist spells entirely in favor of SCH equivalents, which could then be balanced appropriately without touching SMN.

...I like your black/white idea, and am now trying to figure out away to make that into a trait-upgraded Aetherflow, and failing completely. Or at least, failing to think of something that wouldn't likely be extremely broken (Still returning MP, gives charges to both sides). ...maybe if it only charged each side up half way... A suggestion on that idea though; it would probably work better if you crossed the skills. So heals would build up the gauge that you cast the big DPS spells from, and vise versa.

EDIT: I have also seen the idea that that should push it more toward being the "pet healer" like SMN is being pushed more toward being the "pet DPS" with DamiBahamut (as opposed the the "DoT DPS who also has a pet" that they were in HW). Fey Union does seem like it's trying to go in this direction, if they fix at least it's range issue and do something about it being mutually exclusive with Dissipation.
