All the prosperity did was make it so that by having HIGH cost villages, you aren't penalized by Bullshit recovery rates.
With a 25g fief, you would need 1000 prosperity to get 500 goods sold per day. With the new system, that same location can sell 1000 goods in a day. It's a Buff to people who knew(know) anything about basic economics. If you EU's would bother reading all the shit I posted about S/D, recovery rates, transactions, etc, you'd realize that you can't run an economy on the way it was set up.
Loving the tears coming from the ignorant EU's. Stick over there and whore your way into economic libido. I'll stay here and make a proper fief that benefits anyone wanting to make money the proper way.
Also, refund bank already! I want my 10k back!
