What do you think the resource decrease will do for profitability off these 2 activities? I am not sure if lower spawn rates on herbs/ore will actually mean lower prices personally.
The initially higher prices due to scarcity would lead to more farming and more bots, lowering the price again, and keeping it that way for a good while while all the farmers/botters realize nothing has changed in reality due to more herbers/miners. Then prices will go back up when people stop out of frustration, and then people will be attracted by high prices and do it again, ad nauseum.
