League of Legends patch 12.9 will be looking to shake things up quite a bit in the champion meta. Riot Games is set to introduce a good deal of nerfs, buffs, and mid-scope updates for many champions in the coming week. The next update will introduce a lot of nerfs for picks like Sion, Ahri, and Renata. They have been quite dominant in the current meta and have been hard to deal with in both solo-queue and standard matchmaking.Matt Leung-Harrison@RiotPhroxzonChangelists are still subject to change.
