League of Legends Patch 13.20 includes some of the changes that were deemed too disruptive for the Worlds patch, including the K'Sante overhaul, changes to the Jungle role and camps, as well as some anti-snowball mechanics like reshaping the Drakes and Rift Herald and reducing death timers early.

A comprehensive rundown by David “Riot Phreak” Turley, Summoner's Rift Design Team Lead provides a deeper insight into the motivations behind most of these changes.
