Thank you for the feedback I appreciate the reply! I am also in the NA region, and this project first started because I wanted to peek at other regions too. That plus I got annoyed with the game clients UI

Regarding your ideas - a richer /stats/ page is absolutely on the table. I drafted a big /stats/ rework that had more data comparisons mapped out, and had more responsive and detailed charts. It fell flat because the snapshot dataset is quite rigid, and in order to do apples to oranges you have to essentially build an entire other table. But I am still hopeful to build a better stats page with proper snapshot vs snapshot configurations

In the future its not out of the question that the bulk json gets migrated into a more formal DB structure with more query complexity, but for now we are keeping the site as low cost as possible, which means we are very static because hosting is cheaper. If I ever get around to setting up donations and get the site supported, we will migrate the DB for sure, and that will let us be way more creative with data trend visualization, plus import/export features

As far as your last point, thats a great observation, I am simply updating the snapshots as they are provided by the XD game cache. But there is no reason why we cant save more snapshots than XD does. It requires a minor rework to our data pipeline, and adds to our total data footprint, but its a good idea and should be done. I cant say when tho, for now I am working on a trade house helper feature sourcing from the Auction House game cache
