Hey!
The 7.36 Update from May introduced Facets choices for every Hero. These facets would sometimes change talent, item & ability choices. I reworked the algorithm that is responsible for creating hero builds such that you can now chose the Facet of a hero and see available builds for it. There are some other "under the hood" improvements that you won't always see, but the algorithm is now better at distinguishing different builds. Example are shown below.

Hope this is helpful! If you encounter any problems on the hero pages, wittness weird builds that shouldn't be there or think certain item builds are missing, please let me know!
