So as you may or may not know I've been working on updating my Transmog list, and have had a beta list out for testing for a while now. Thanks to feedback from both Nick H as well as Bones in this post, as well as additional data from the TSM API, I was able to further refine this list, and come up with a (for now) finalized list.
The TSM API
Thanks to the hard work of the TradeSkillMaster team, you can now pull data from some price sources into an excel sheet for analysis. If you are interested in getting your own data, check out this post by Sapu on The Consortium for instructions on how to get your own data. I am thinking about writing a post on how to import this, and some tips on how to utilize the data in the future. I know Stede mentioned in that post that he's working on creating a sandbox.
