ADC nerfs will shake up the bottom lane meta

Throughout League of Legends Season 12, a number of marksmen have been at the forefront of the meta. At first, it was a two-headed race of Aphelios and Jinx to start the year but come Zeri's release, this has changed.

However, LoL 12.5b will take a look at these picks. In an effort to scale things back, some new nerfs are coming. For Jinx, it'll be the first time she gets a balance change this year while for Zeri, it'll be yet another buff.

This is supplemented by several buffs going towards the likes of Ashe, Draven, Lucian, and Varus who haven't been as favorable as the aforementioned three. Depending on what changes are made, this is sure to shake up the ADC meta in bot lane.

Master Yi to get some buffs after massive nerfs

After a standalone nerf followed by a hotfix, the Wuju Bladesman got hit hard, dropping his winrate to 29.6 percent in Diamond+ and 41.6 percent in Silver.

As a result, Riot has added him to the list of champions to buff in LoL 12.5b hoping to balance out his previous changes.
