For some reason, Blizzard decide to don't give the players the chance to pick map or side (attack / defense) when you play Overwatch.

Do you want to play Dorado over and over so you can get the hang of it? Tough luck. Want to avoid King Row's because you think it's boring? Nope.

Maybe it's because it's beta and they want us to "test" all the maps but I sure hope when the game is launched they give the players the freedom to pick the map they prefer.
