Big changes are on their way in Y9S1 of Rainbow Six Siege, as ADS adjustments look to tackle the dominant 'TDM Meta', and nerfs to Azami might challenge her status at the top of our Operator tier list.

These aren't the only adjustments coming at the start of the game's ninth year though - far from it - with other balancing revisions to other Operators, revisions to the various optics, and even a number of changes to the many LMGs too.

Patch notes for Y9S1 in Rainbow Six Siege

Operator balancing


  • Kiba Barrier
    • Barriers now have 999hp
    • Barriers are now vulnerable to bullet damage
    • Damage dealt to the barriers depends on the weapons' calibre or destruction output

This is a big change to negate the overwhelming power of Azami on Defense. Previously her barriers could only be removed by explosives, which meant that Attacking teams had to cater their approach and selection around this.

They will still be a pain to take down, and something that could reveal your position and expend your resources, but I'll now feel a lot more confident running a flank without any explosives.


  • Adrenal Surge
    • Weapon reload speed increase bonus removed
    • Clears the sheilds' Suppressive Fire debuff, and reduces its effect by 50% if applied while affected by Adrenal Surge

This has less to do with Finka and more to do with the new attachments, as it highlights the effectiveness of the new Angled Grip. Furthermore, it ties in nicely with the Shield rework - and something that I'll be trying to coordinate as someone who enjoys picking up the Russian Operator.

Weapon balancing


  • New classes:
    • Revolver
    • Sniper Rifle
    • Slug Shotgun

Light Machine Guns

  • Movement speed reduced by 10%

ADS transition

  • Normalised and simplified ADS curve transitions:
    • Fast:
      • Handguns, Revolvers, Shotguns
    • Medium:
      • Marksman Rifles, Sniper Rifles
    • Slow:
      • Machine Pistols, Submachine Guns, Assault Rifles, Light Machine Guns, Slug Shotguns

ADS speed

  • Reduced ADS speed from idle/walk stances:
    • Handgun: 240ms (from 200)
    • Revolver: 240ms (from 200)
    • Machine Pistol: 380ms (from 280)
    • Submachine Gun: 460ms (from 300)
    • Assault Rifle: 520ms (from 400)
    • Light Machine Gun: 560ms (from 450)
    • Marksman Rifle: 520ms (from 400)
    • Sniper Rifle: 520ms (from 400)
    • Shotgun: 340ms (from 250)
    • Slug Shotgun: 520ms (from 400)
    • Hand Cannon: 240ms (from 200)
    • Reduced ADS speed from sprint (same proportion)
    • Launchers are also affected. The ADS Speed depends on the type of sight

This is a significant nerf to run and gun playstyles that have been at the forefront of the meta for a while now. You'll now have to be much more intentional about when you aim down sights and might find yourself caught out if you try and aim reactively under pressure.

    • Magnification: 1.0x
    • Added +10% ADS speed bonus

Under Barrels & Grips

  • Laser
    • Removed Hip Fire bonus
    • Added +10% ADS speed bonus
  • Angled Grip
    • Removed ADS speed bonus
    • Added +20% weapon reload speed
  • Horizontal Grip
    • Added +5% movement speed bonus
  • Vertical Grip
    • Bonus reduced to +20% vertical recoil control from +25%

This should make all of the underbarrel attachments viable and relevant to each specific weapon, giving you an actual decision to make when kitting out your gun.

I love the ADS speed increase being tied to the laser, as it's what many players will want to go for but comes at the downside of having a visible laser in-game.
