Why not start the Shedu with Astral 3 Earth 3, instead of 1? Let him be strong in those paths since he will pay dearly to have any others (and you're pretty much forced to buy Astral pretty high anyway to protect against Magic Duel). He already has a high base point cost, why doesn't he get anything much for it?
Limited magical versatility and item use is still a bit of a problem, but he can now much more cheaply get a level of magic power that can make him a contender on the battlefield doing something like Power of the Spheres, Summon Earthpower, Blade Wind x3. Compared to other battlefield mages he is pretty tough even without casting defensive buffs. So once the usefulness of body ethereal, stoneskin, attack rear is exhausted, he can start standing behind bodyguards and troops and casting powerful spells over them.
Oh, and those chariots that are so crappy? Not once the God casts Legions of Steel/Marble Warriors and Will of the Fates on them... Riches from Beneath will offset the problems of a mandatory sloth dominion, if you can afford it.
As for Golden Age: I like the idea of myrmidons being more of an elite unit in skills/morale. They may not have modern equipment but they can fight like the heroes of old
Awe on the wind riders seems cool too - and they *are* more expensive than Valkyries for little benefit. And I agree that Golden Age needs something magically to make up for the loss of the Astrologer, although I don't know what. Stronger or cheaper Mystics, a new mage, or maybe an arch-priestess with Nature 2 Holy 4 (making them a strong-priest nation)?
Hmm, I just had an idea. Give them the three Metal Adepts as capitol-only mages (perhaps a new capitol site, Metallic Tower?). They're astral and elemental, so they don't do anything a Mystic couldn't theoretically get; but they give you more predictability of what elements you get. Plus two of their elements are air and earth, which Golden Age Arco gets gems for. Best of all it requires almost no work to implement because the units already exist
