Erickson: For many an Overwatch player, playing in the competitive game mode often feels like rolling a pair of dice. Especially if you are playing in solo queue. Its not uncommon to find yourself on a team full of DPS players or that the entire enemy team is Mercy mains. That is the sad reality of Overwatch. Player skill does not determine the outcome of most matches, they are won or lost at the hero select screen.
