Would you pay for unsoulbinding item?
Never! I would certainly never pay real money for that sort of thing. If I am to buy it with gold then I could probably buy another with the gold spent on the item.
The only possible exception I can see here is Legendaries and for that I would rather see them made permanently account bound like the Ancient Karka Shell. That is IF they are every going to consider such a thing, not suggesting or requesting that they do.
