Rainbow Six Siege's latest DLC, Operation Chimera, is coming to PS4, Xbox One, and PC on March 6, and with it now live on the Technical Test Server, Ubisoft has released its patch notes. In addition to adding the two new Operators, Finka and Lion, and the new co-op Outbreak event, the update introduces some gameplay tweaks and changes a bunch of Operators.

Ela has been a popular pick since her release, but she's to be nerfed in the new update, as Ubisoft believes she is still "picked way too often." Her SMG will suffer from increased recoil and deal less damage than before, and her impact grenades have been replaced by a deployable shield. "She was too good at doing all the roaming work by herself," the developer said, "preparing rotations, being warned by Concussion mines, and of course killing with her SMG. This loadout change will force her to rely on teammates for rotation holes, or to pick the shotgun if she wants to do them herself."
