While Blizzard has already said that it would be saving significant hero rebalancing for Season 2 of Overwatch 2, the Californian developer has now published a forum post highlighting some of the changes it has planned for some of the more oppressing characters.
Specifically, it is Sombra, D.va, Zarya, Kiriko, and Genji who are receiving slight balance changes, with those being:
Sombra
Hack ability lockout duration reduced from 1.75 to 1.5 seconds
Hacked enemies are no longer valid targets for hacking for the duration of the effect
Hacked damage multiplier reduced from 40 to 25%
Genji
Maximum ammo reduced from 30 to 24
Shuriken damage reduced from 29 to 27
Zarya
Barrier duration reduced from 2.5 to 2 seconds
Barrier cooldown increased from 10 to 11 seconds
D.va
Fusion Cannon spread increased from 3.5 to 3.75
Boosters impact damage reduced from 25 to 15
Kiriko
Swift Step invulnerability duration reduced from 0.4 to 0.25 seconds
Interestingly, one of the most used and oppressive characters currently in play, Sojourn, will not be receiving any changes, likely to the dismay of many players.
As for when these balance changes will be arriving, the aim is to have the patch arrive in an update on November 15.
