On Wednesday morning, Riot Games' unveiled their 9.14B patch notes which aim to create more of a balance on the battlefield and knock a few popular strategies down a couple of pegs. 

With Brawlers, most specifically Volibear, and Ninja/Assassins dominating the current meta, a reduction to their overall power level is what the developer team looks to accomplish when the patch goes live later today. The developer comments alongside the patch notes themselves provide a bit of insight into the design process:

"In these B-side patches we'll be making changes focused on balance and bugfixes. This week, the biggest change is to critical strike modifiers with the aim of toning down the damage Assassins bring to the table. Additional highlights include: Volibear and Cursed Blade getting nerfs, while Sorcerer and Wild get buffs."
