You can now use the TBC Optimizer! You will find a TBC link on the home page and at the top-right of most pages on the website.
Go to https://www.askmrrobot.com/the-burning-crusade to get started!
The TBC optimizer includes Best in Bags, the Upgrade Finder, Worst in Bags, and Best in Slot. They are all premium features, and everyone gets a one-week free trial.
We did a lot of research and created mathematical models for every spec. The optimizer runs this model on the fly as it sorts through all of your gear. This is a bit different than the simulation approach used for retail WoW. We decided to go this way for TBC because the game mechanics lend themselves to such an approach much better than retail, and it gives us a lot of extra flexibility.
Here is the main blog post describing it:
TBC Gear Optimization
Please let us know if you have any feedback or run into any issues. We did our best to catch most things, but there are always little tweaks to be made. We thought it was better to release it now rather than delay it further to continue testing.
We have a few small tweaks to some of the gem optimization to make still, but it shouldn’t make a noticeable impact for most people.
