League of Legends developers shared the preview for patch 13.3. Kayle, Lee Sin, LeBlanc, and Jarvan IV expect buffs, while Zac, K'Sante, and Amumu will be nerfed. The information was posted on Twitter by Matt "Phroxzon" Leung-Harrison.
He stated they want to prioritize early ganks over farming "in the short term."
We're looking at jungle dive power and rewards for ganking vs farm. There's more to do on Jungle, but we want to hit early gank power (esp for bot lane) in the short term. We're also getting 13.2 changes that couldn't make it in due to tech (overheal, multiplicative tenacity).
Kayle's update has nothing to do with the ultimate rework that was recently teased. Riot's August added that the PBE testing "felt pretty good," but the animation changes will take time. These buffs are a temporary solution before the new version of Kayle arrives.
Patch 13.3 with Ahri's ASU will be shipped on February 8. The adjustments for tank supports mentioned in the patch preview were detailed previously by Riot's Phreak. You can learn more about them here.
