The idea that 'traditional' methods of farming do not change the landscape is ridiculous. I don't know if you've ever been to the little island where i'm from, Great Britain, but, the whole island used to be wooded. Now, it is completely covered in fields seperated by dry stone walls. That is not intensive farming, not even remotely close. It is hundreds of years old, 'artisan' farming. And it has literally completely changed the entire landscape of my country.
Also Zelot, your point about how the AFA is an amalgam of a bunch of different things and is 'impossible to define' is what I meant when I said you have completely changed the vanilla RP of the faction.
