A preview of League of Legends patch 26.12 has been released, indicating that several champions, including Lee Sin, will be nerfed. The patch is expected to bring significant changes, potentially affecting the top and mid lane meta, with some outlets reporting nerfs to Varus and Xin Zhao, while others mention Ryze. The exact scope of the changes is not entirely clear, but buffs to certain champions, such as Aatrox, and adjustments to teleport are also mentioned.
