LoL Patch 12.15 Notes: Energy Champion Changes and More


League of Legends patch 12.15 is a day out from hitting live servers. Here's all the info on LoL Patch 12.15

As the design team hinted before, the patches in the run-up of Worlds will be smaller in scale and try to optimize the meta to offer the best balance during the event, and still keep the balance on the non-competitive side of things.

What is changing with 12.15?

As we said, 12.15 is not a very heavy patch. There aren’t many nerfs to champions and most of these are focused around the pro play. Gwen, Kalista, Sivir and Taliyah are all near pick/ban in major leagues and are getting nerfed. And among these, only Sivir and Taliyah are necessarily played in solo queue but their changes are mostly around their ultimates, which are heavily skewed towards competitive, so you should not feel too much of a change in your games. The bigger nerfs for solo queue are Master Yi and Qiyana, and a bug-fix for her, ones. Master nerfs should especially be good for lower elos where he once again is very prominent and strong.

The largest change of the patch 12.15 should be the energy champion buffs. All champions who use energy as a resource got some buffs to either their regeneration mechanics or their spells’ cost. The only exception to this is Kennen, as he doesn’t struggle with energy costs too much. However, Kennen is not a champion with a high pick or win rate so he is getting some damage and cooldown buffs. The changes are mostly about giving him power in late-game team fights.

There are also some system changes, but once again not too many. Divine Sunderer is once again getting nerfed, but do not worry as Trinity Force is still a very good option for most champions. The two Quicksilver Sash items are getting some buffs, which is great as players did not feel good about converting their QSS to a full item. This means QSS is a much better option in most games considering the amount of CC in the game.

League of Legends Patch 12.19 Preview

Solo queue system changes

Aside from in-game changes, there is one more big shake-up in this patch that will affect the high-ranking players. Ever since the 2021 pre-season players that were ranked Master or higher, which Riot calls Apex Tier, were not able to duo queue. The change was somewhat divisive among the player base as many enjoyed playing with their friends, but also many did not relish having a duo on the enemy team.

This change resulted in a situation where players would duo queue to their Diamond promos and repeatedly dodge lobbies to fail those said promos. This would let them stay in Diamond, and thus be able to duo, but their Matchmaking Rating (MMR) would continue to rise as they wouldn’t actually lose games. This meant players could still duo and play against Apex Tier opponents.

To prevent this situation, Riot made a change in patch 12.10 that disabled duo queue for not only players in Apex Tiers but also the ones who are in lower ranks with Apex Tier MMRs. The change was implemented in NA and Korean servers as a test, and after successful results Riot is bringing the changes to all other servers.
