Blizzard today shared more information about recurring items in the Trading Post. You should feel comfortable passing on items that aren’t your first picks in a given month, because they will return in the future.

Hello. Thank you for the feedback. As the Trading Post is still quite new, we’re taking in all the written feedback we can get. We’re also informed by the data we’re getting each month on which items players prefer, which activities they earn tender from, how early in the month they make their purchases, and many other points of information.

We do want to note that items will return and become available again in the future. You should feel comfortable passing on items that aren’t your first or second choice choice in a given month, knowing that you’ll see them again. We’re focused on making a system that has a long term impact.

We will continue to carefully examine the Trading Post, and discuss everything about it, and make changes when necessary. We don’t have anything along those lines to share at the moment.

Thank you.
