I must say that I aprove the idea of units with whips/sickles/scythes.
Perhaps Judges and Warrior judges could be split into two, one more mage-like and another more of a renown warrior? Though multiclassing is fine by me, too.
Giving astral to the prophets would allow them to participate in Communion with the Judges, and that could be a critical advantage for a nation with very light troops. Astral + elemental pics sounds good to me.
The Levis and Religious Scholars are kinda overlapping...but maybe we'll figure something for them. Maybe an elemental random for the Religious Scholar? Mist-pillar making must start somewhere.
Standard would be good for the commanders, at least the light troops would be inspired ones.
I also like the hero ideas, but I think that Elyahu Clone could have Astral. Astral + Elementals is very Arco-like I know, but Astral also allows the Angel summons which are very fitting to say the least.
I like it so far, if you get any ideas forward them to me.
