2 weeks since EA made the Trade HQ worse and still no fix. I have not even heard EA admit there is an issue.
I have very fast devices and several internet connection types that are the fastest possible, and most valued items are still gone before I can purchase them. Even common items are gone. Do you have to be right on a backbone to be fast enough? Or in the right city?
The user story is easy guys: As a player, if I see an item listed and click on it in a reasonable amount of time, I should be able to purchase that item at least 90% of the time, so that I reduce the amount of time spent trying to purchase a sought after item, and ensuring that the game is less frustrating.
You can make assumptions that players have a typical internet connection, and common devices.
I will say this, though. Anything I try to sell seems to be much more successful than previous versions. So, the acceptance criteria has to keep in mind to minimize the impact of our items selling ability. For me, EA got the selling part right.
Filtering the list is a new feature and should be a lower priority to fixing it. You should not add features until you fix the issues.
Frustrating!
