There’s some bad news for Overwatch players tired of Mercy’s repeated changes and nerfs. Blizzard will make changes to Mercy along with four of Overwatch’s five other support characters in the next patch.
Announced by Lead Designer Geoff Goodman in a forum post yesterday, the changes are meant to keep the support characters competitive with one another. In addition to Mercy, Ana, Brigitte, Lucio, and Moira are all getting changes. That means Zenyatta is the sole support character who will remain unchanged, with Goodman explaining that Zenyatta’s “doing his job well as a hybrid damage/healer, and being able to provide discord orb for your team will always be welcome.”
