Ive noticed a problem with treasure cards, as you level and get up into level 70+ you get treasure cards by the mass, alot of which you dont need, but in order to sell them at the bazzar you have to sell each one individually, so in short i think a good game idea would be to impliment thing in the bazzar that would allow you to sell certain item such as treasure cards at bulk, allowing you to check mark the cards you want to sell, and this would actually work for all item you are selling.
