I am with Alvin on this. I agree we need to find a balance here. I am speaking from experience here. I have 4 traders and 2 miners. I rather enjoy trading. though,with help mining, it is possible to earn 52 mill an hr.
I am not sure if the fix is either:
increase trading profits.- which would increase the number of trade runs etc
simulate a dynamic commodity system: by changing prices say once a month
change ore sale prices or add more sale locations.
I am also sure that alot of this can also be attributed to the delay of the release of 4.86
everyone is waiting to see what happens. which can also affect activity.
