League of Legends patch 12.15 will go live next week and there are a few updates that have been
planned by Riot Games in it. Although 12.15 won't be a complete disappointment for the current
champion meta, it will bring a few changes to make things smooth enough for some of the
champions in the game.

The most important highlights of the update are the buffs that will be received by the energy
champions. Thus, it can be said that Akali, Shen, Zed, Kennen, and Lee Sin will get quality-of-life
updates. Only Master Yi and Sivir have seen a significant number of tweaks making their way to the
kit. But they will be toned down a bit in League of Legends patch 12.15.

Riot's proposed changes will first be introduced in the League of Legends PBE 12.15 cycle and only
after a thorough study, the updates will be officially made along with the final patch next week.
