We have posted an updated economy proposal in the Ideas section of the forums and invite you all to check it out.
Right now the proposal exists as proposal 1.0, split into three posts – overview, trade, shops – and as proposal 2.0 which is a post with only the updates/changes to 1.0. That means that if you have not acquainted yourself with 1.0 yet, it would be good for you to do so because 2.0 only touches on a handful of aspects and differences. It is safe to assume everything not mentioned in 2.0 is the same as in 1.0 still.
Please let us know what you think!
