What new mechanics or features have been added in the latest Overwatch updates and how has it impacted gameplay?

In Season 10, a new hero named Venture was added, who can move underground. You can see all his abilities in this video: https://www.youtube.com/watch?v=KixkgmyNF0E
However, the hero has a minor impact on the meta, as his shooting distance is short, and in other aspects, he falls behind many other damage heroes.
