Rainbow Six Siege Y5S4.3 Patch has been released on the test servers today, and it introduced a lot of new changes to the existing operators in Siege.

Operation Neon Dawn’s mid-season balancing patch is finally here, and Ubisoft has tweaked many operators to bring their effectiveness and popularity closer together.

We reported on a leak yesterday, which stated that Zofia would be losing her Withstand ability, and now it seems like the leak was indeed correct. With Patch Y5S4.3, Ubisoft will be removing some of the “hidden” mechanics of the game, which means the passive abilities of Zofia and Ela will finally be gone. So Zofia will no longer be able to withstand, and concurrently Ela is also losing her “extra” mine.

Ash will also get a slight nerf on her breaching rounds. On the other hand, Buck will be getting more ammo on his shotgun, and Echo is receiving some quality of life changes to make the drones feel snappier.

Read the full patch notes down below (via Ubisoft).
