League of Legends Patch 13.21 introduced massive changes for Dr. Mundo, Rammus, Seraphine, and Tahm Kench, but the next patch will look to revert some of these buffs and nerfs.
On Oct. 31, League lead gameplay designer Matt “Phroxzon” Leung-Harrison shared the Patch 13.22 preview, revealing Riot “swung a bit too far on these champions, especially Seraphine for solo lane.”
