Final Thoughts

These are the changes that you will see in the PTR for Season 16. Some of these were only slightly mentioned in the patch notes, and missing information or just not mentioned entirely. These changes are minor, so nothing should completely change any builds.

If any new undocumented discoveries are made, they will be updated in this article.
