The most recent Overwatch PC patch - version 1.0.4 - has made a few changes to heroes that were previously packed a little too much punch. McCree and Widowmaker were a little too powerful for their own good, so got dialled down a little. You can read the patch notes here, but we've given a quick rundown below.
McCree's alternate fire, fan the hammer, now does considerably less damage, with the bullet damage reduced from 70 to 45. To compensate, the recovery time (the amount of time before he starts reloading) has been decreased from 0.75 to 0.3 seconds. According to Blizzard, this was to curb his ability to shred tanks:
"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 has also received some nerfs to her damage. Her scoped shot base damage has been reduced from 15 to 12, meaning a fully charged shot will no longer outright kill a Tracer or Zenyatta. In order to balance it out a little, her headshots no longer deal 2x damage, but instead 2.5x damage, meaning a headshot will still do the same damage as it did pre-nerf. On top of this, her ultimate charge time has been increased by 10%.
"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."
Along with the patch notes comes the news, via a Tweet, that Overwatch now has over 10 million registered players, and the number is still growing.
