As an addition...why not.
Now what really seems worrying...
How to determine the right value?
Abuse by shifting gold to one certain player, who, afterwards is able to boost his looms?
(chadz wanted to keep loomed items minimized-allthough impossible alltdy-this could make it worse)
Value of gold decreasing in the long term, by actually having a higher amount thrown on the market,
which would make it harder for casuals (maybe)
But all in all, if done right, it could be a good add...not that easy to add as it might seem in the beginning.
