The recent fiasco about Yae Miko’s Elemental Skill stemmed from changes implemented when Version 2.6 went live, which changed her targeting mechanic to prioritize the nearest enemy. This was largely viewed as a nerf to her kit, as it completely invalidated her expensive C2 upgrade and didn’t account for all battle scenarios, rendering the skill useless against enemies with shields.
In response to the community’s anger over the incident, Genshin Impact took to its official channels to address the issue. In an apology letter, the game acknowledged that they didn’t consider all combat scenarios during Yae Miko’s targeting modification, which considerably impacted the player experience as a consequence.
