It will be the last set of tweaks that will make their way to the MOBA with the 2022 World Championship in focus.The pre-notes for the upcoming update have finally been revealed by Riot Games. It seems that Udyr will be in for a lot of adjustments, while Ashe and Lee Sin will be up for some buffs.Nerfs will also make their way to Kalista and Lulu as the League of Legends developers look to balance the bot lane duo ahead of the international event.Matt Leung-Harrison@RiotPhroxzonGenerally going for safe changes this patch so we can target accurately. There's a decent amount of unknown, with 12.16, 17, 18 having no Pro Play exposure, but we're relatively confident we'll be in a good spot post these changes. Udyr changes are buffs to DPS and nerfs to Tank1295181Generally going for safe changes this patch so we can target accurately.
