This rework is now live on the test servers ahead of its official launch, for folks who wish to check it out, and that update also includes extra colourblind options.
Turret-tapping notdwarf Torbjörn is next in Overwatch‘s queue for an rework, replacing and remaking some of his abilities to make him more flexible.
And Molten Core, his Ultimate, which did buffing before, is replaced with a new skill confusingly also named Molten Core.
Blizzard tend to give character reworks a good ol’ testing, so it may be a few weeks before this update hits the live servers.
