Rainbow Six Y5S2.1 patch notes: Melusi nerfs, Match Cancellation, more

Andrew Amos

The first balance patch of Operation Steel Wave has arrived in Rainbow Six: Siege. New defender Melusi is bearing the brunt of the changes with some big nerfs to her Banshee, although attacker Ace hasn’t escaped untouched either.

Operation Steel Wave has been met with mostly positive reviews. Ace and Melusi have both brought something new to Team Rainbow, and the new House rework has been considered a success.

However, there’s been some issues with how strong the two new operators are. Thankfully, in a June 30 patch, Ubisoft have looked to rectify these issues. Melusi has been hit with the brunt of the nerfs, targeting her oppressive Banshee gadget specifically.

Melusi in Rainbow Six Siege
Melusi’s Banshees have been hit hard on Y5S2.1.

That’s not all the Y5S2.1 patch is bringing though. Match Cancellation is finally being added, which will be music to the ears of ranked warriors everywhere.

Melusi’s Banshee gadget nerfed

While Ace has landed in a good spot following his introduction in Operation Steel Wave, Melusi has been a bit overpowered. The three-speed defender is a nuisance for attackers to deal with, especially when you consider how powerful her Banshee gadget is.

Thankfully, in the Y5S2.1 patch, her Banshee is getting nerfed. Its radius has been reduced by 33% ⁠— down from nine meters to six. The sound of the Banshee effect is also being lowered somewhat.

This change will make it so Melusi players are rewarded for good positioning of their Banshees ⁠— not just dropping it anywhere. It’ll also make them a bit easier to avoid as attackers with a smaller radius.


Match Cancellation feature added

After being floated at the Six Invitational, a long-awaited feature is finally coming to Siege ⁠— Match Cancellation.

The feature “will allow players to cancel their current Rnaked match under the condition that team sizes are unbalanced at the beginning of the match,” Ubisoft stated in the patch notes.

The team which is down players will be able to vote on canceling a match, with a majority vote terminating the game. Players who don’t connect will be given an Abandon penalty. A player’s MMR will not change if a match is canceled.

Hibana in Rainbow Six Siege
Hibana and Ace’s gadgets have also been adjusted slightly.

On top of these changes, Ace and Hibana will no longer be able to destroy fragile gadgets on the other side of reinforced walls with their hard breaching devices. Various bugs have also been squashed, including a bug which allowed Echo players to see through ceilings on their drones.

Game Updates

Match Cancellation

Match Cancellation will go live with the Y5S2.1 update! We have tested it on the TS and as well as internally against a number of potential circumstances. However as it is a new feature, please let us know if you have any feedback or issues to report with Match Cancellation at r6fix.ubi.com.

Match Cancellation is a new feature that will allow players to cancel their current Ranked match under the condition that team sizes are unbalanced at the beginning of the match (eg: if players disconnect before the first round, or if a lobby is formed with less than 10 players). The Match Cancellation vote option will become available for the incomplete team during the prep phase and a majority vote will cancel the match. A canceled match will show as canceled and have no impact on MMR.

Abandon penalties are still in place and players who abandon an ongoing Ranked Match are still subject to escalating abandon sanctions.

If a match cancellation vote is triggered, leaving before the validation of the Match Cancellation vote will also result in an abandon penalty. Players should remain in the game until the Match Cancellation vote is validated and the game has been canceled.
