Overwatch has been on the market for less than a month, but already some glaring balance issues needed to be addressed. And to Blizzard’s credit, they are addressing them in quick fashion:

McCree

Peacekeeper

Alternate Fire
Recovery time (i.e. the amount of time before McCree starts reloading) decreased from 0.75 seconds to 0.3 seconds
Bullet damage decreased from 70 to 45

Developer Comments: McCree was performing too well against all targets, making him feel like a must-pick in many situations. By reducing the damage of his alternate fire, McCree is now significantly weaker against tanks like Roadhog and Reinhardt, but still maintains his lethality against smaller targets like Tracer and Genji.

Widowmaker

Widow’s Kiss

Alternate Fire (Scoped Shot)
Base damage decreased from 15 to 12
Note: Scoped shot damage multiplier remains unchanged
Headshot damage multiplier increased from 2x to 2.5x
Players must now wait for the unscoping animation to completely finish before scoping

Infra-Sight

Ultimate cost increased by 10%

Developer Comments: In the right hands, Widowmaker can often feel unstoppable—even when just landing body shots instead of critical heads shots. The changes to her alternate fire weaken body shot damage while leaving her headshot damage unchanged. Additionally, we felt her Ultimate ability, Infra-Sight, was coming up a little too frequently, especially considering its impact on the game.

Bug Fixes

Fixed a bug that allowed Reaper to Shadow Step to unintended locations on certain maps

Maps

Fixed an issue with collision on certain areas of Dorado not blocking line of sight

Thoughts

Tanks can finally face McCree without fear of being taken down with a single Fan the Hammer! But everyone else will still die. Sorry everyone else… For all those McCree players crying about this change being a nerf, it was necessary. No character should be able to take a full health tank down with one move. This is a balance change and a needed one at that. Every stream I watch of professional players has a McCree on both teams. There’s a reason for that.

As someone that plays Zenyatta frequently, I’m very happy to see this Widowmaker change. Before the patch a body shot would deal 150 damage, after the patch it deals 120 damage. Full health Zenyatta takes 120 shot and has 30 HP left. After his shields regenerate he’ll be at 130 HP and can survive another body shot. This pleases me.

I don’t think a sniper should be able to kill any character that’s full health with a body shot. Headshot? Sure! But being taken out at full health by a shot to the foot? Not cool. Bravo Blizzard.
