Ask HN: Anyone here play Warcraft? (feedback on a project requested)

If you play World of Warcraft, please check out my latest project:

http://www.trackwarcraft.com/

The site quickly gathers data from the Armory, analyzes it, and presents it in an easy to glance at format. It's built on App Engine so hopefully it won't die under load like other similar tools. The site also lets you do parallel look ups of multiple characters. The big risk is if the Armory throttles my look ups -- I'm doing caching and back-off if I'm throttled. All of the URL fetches are parallelized which has shown to be an order of magnitude faster than other sites.

Any feedback is appreciated. The site could use some graphic design and UI work. If you have suggestions, or you'd like to help, please let me know! :)
