Overwatch fans have not been happy with Reinhardt ever since the Anniversary event kicked off this week. The latest patch apparently screwed up his overall hit power and swing with the hammer, and his only really registering after a full swing of the hammer in the middle of the screen. Essentially nerfing him and making him ineffective as a tank beyond his shield. Reddit went insane with comments about the changes when there was no notice made saying this would happen and cited it as a bug.
Bill Warnecke, the Overwatch lead engineer jumped online and replied that the nerf was in fact not supposed to happen and that they would immediately look to fix the issue. This is actually the lesser of the two problems fans have had with the Anniversary event, the bigger being the concern fans raised over how much it would cost to unlock all the new content in the short piece of time, which roughly came out to almost 57k of in-game credits. That's the most expensive event in the game's year-long run, and unless you are an amazing player with equally amazing luck, you're not coming close to getting all of those items. And as we've discussed before, the odds aren't really in your favor.
Hopefully, all this will be put to rest once Season 5 kicks off.
