Some things I'd maybe like to get done for alpha 24's release:
Come up with some new socio-economic paradigms for some of the civs. Not all civs should have the Slavery paradigm.
Mauryas: Caste-based system
Celts, Iberians, Persians: Some kind of peasantry-based system
Balance Elephant Archers some more
Probably make their ranks increase their attack since I can't add arrows
Convince some talented people to make more Cult Statues for the
