This week brings us patch 6.18, which is the patch that Worlds is going to be played on. There are some huge changes in here for champions that are big in the competitive scene as well as the release of Yorick’s rework.
This patch is very obviously focused on the competitive scene, with most of the balance changes following champions that are big professional hitters. (What will Cloud9’s top-laner Impact do about the Gnar nerf?)
