That's actually my biggest issue with moving sorcery. As I said earlier, since you need 10XP on an adept to get a mage, there is a natural limiting process to how soon you can get a T3 unit even if there is no intermediate tech between KotE and Sorcery. However, with the Amurites' Cave of Ancestors, it is not difficult to get enough mana to get mages right off the bat...
wait, I just realized that the mana node techs would be after Sorcery, so you couldn't get enough mana off the bat, and the mage spam would still be limited. You could still do it with apprenticeship, form 'o the titan, conquest, 3 mana from the palace and one from a religious shrine, but that is a lot of side-teching and conditional stuff, so it'd be okay.
