I looked through the suggestion list and didn't see this in there. I apologize if it has been suggested before.
I think it's a shame that the player shops are so underused, and I feel like a few changes could be made to improve commerce of "find-able" gear and items between players. This might be tricky to implement, but I think this would liven up the game market, and the game in general.
I propose that each player shop feature a section where he/she might specify the item that they wish to acquire, and the price they are willing to pay. It would probably be too hard to provide a database of items through which we could navigate, and select an icon for the specific item we want... so, maybe we could just have it be typed out. It would also be great if we could consult statistics on recurrence of solicitation for items. If I could open the player shop and see a list of the top requested items with a "hot" tag on them, that would be amazing.
What do you guys think?
