I’m not very well updated in all things blizzard, and only really play Diablo and Overwatch when it comes to Blizzard games. But I used to be an eager CS:GO player until I burned out, but something they did with their matchmaking was allowing to filter out maps you didn’t want to play. I want overwatch to develop a similar feature allowing you to choose between maps and game modes.
A different competitive game I used to play a lot was League of Legends who would also allow the two teams to ‘‘ban’’ 3 champions each before starting each game, this might not be right for Overwatch with the limited selection of heroes. But goddamn I hate Doomfist and Brigitte, being able to just disable them from my game would save me from a lot of frustration.
