The latest Overwatch update is now available in the Public Testing Region, and this new update is making some changes to Mercy and Ana. Since it’s only in the PTR, there’s a chance that this update won’t be rolled out in its current state to all users, but only time will tell as the changes are being tested. If you want to participate in the Public Testing Region, you’ll have to own Overwatch on PC.
Blizzard has broken down the changes:
Ana

Biotic Rifle

Damage increased from 60 to 70

Developer Comment: Ana has been outshined by other support heroes lately. Boosting her damage will help her defend herself and make her more threatening to the enemy team.
Mercy

Resurrect

Cast time increased from 0 seconds to 1.75 seconds Mercy?s movement speed is now reduced by 75% while casting
Can now be interrupted when Mercy is knocked back, stunned, or hacked

Valkyrie

When activated, Resurrection no longer has a cast time

Developer Comment: We feel that Mercy?s recent rework has been successful, but her Resurrect ability still feels too strong and frustrating to play against. Now that it has a cast time, there is more room for enemies to counter the ability. However, casting Resurrect happens instantly when Valkyrie is active. This should make her feel powerful when she transforms on the battlefield.
Essentially, Ana is going to get a bit of a buff, while Mercy’s new Resurrect will be nerfed.
