This is honestly the best thing that can happen for Overwatch right now. We need a way to avoid players who are griefers and toxic and really do destroy the game experience. This is not permanent, it's only a week, but I think you will find a lot of people are less frustrated and in turn 'toxic' because they now have a way to deal with people whom are awful human beings and actively try to hurt the game. This is good. If you're not an awful person you shouldn't have anything to fear. Instalock Genji/Widow/Hanzo and don't switch when countered and actively harm the team? Bye felicia!
