[Official] Reform requirements - as at 2.3

[QuintusSertorius]

What are the cities for the Pahlava reform? The description is kinda confusing cause it mixes cities and regions.
Also what is the name of the level 4 farm and what gov type/city level does it require?
I hope it's not too high cause I had to sack these cities since they had 0% of my culture ;__;.

Asaak, Hekatompylos, Ekbatana and Rhagae are the names of the cities.

It's called Large Scale Farming and requires a City (ie 6000+ households).
