The idea here, and in my opinion, is not to get rid of Sprawling, or of the flavor of the Kuriotates. Their megacities are maintained (the capital), just toned down a bit. I actually enjoy playing as the Kuriotates, but I find the current rules governing them oppressive--it makes them very much one-track with little room for creativity. I think reworking what it means to be Sprawling would greatly improve the uniqueness of the Kuriotates as well as the strength of the Kuriotate AI. A Tolerant/Sprawling/Philosophical/Expansive Cardith with cities of immense culture and size but restrictions on expansion (maybe with a Palace that doubles city count maintenance or something, and closing off the Palace Tolerant problem rather than Settlements) would really go a long way.
