Yunara buffs, Qiyanna nerfs, and extra

The League of Legends patch 25.21 preview is now out. The next updates are mainly intended to make the Midlane role more interactive, with nerfs to Second Wind, Doran’s Shield, and Catalyst of Aeons. However, the Catalyst should still be a viable option for immobile mages to fight Assassin and Skirmisher champions.

Here are all the upcoming changes shared on the League of Legends patch 25.21 preview notes.
