In a developer update Thursday afternoon, Overwatch game director Jeff Kaplan addressed a number of popular topics in the community. 

First up, Kaplan talked about the ongoing toxicity issues that plague the game, saying that minimizing toxicity is a major initiative for Blizzard and the Overwatch team. He said that the recent updates to the reporting process, such as informing players when an account they report has been sanctioned, has increased player reporting by 20 percent and decreased incidents of abusive chat in competitive play by 17 percent.
