Competitive play is hard especially as you never know who you would be facing against. This includes both the people you would be playing with and the people you would be playing against. Usually however, the teams are set up to be fair so that there are people of equal skill on both sides. Nevertheless, it can be seen in game that teamwork is a powerful and necessary skill required to win each match. As it can be seen in the image from the game, the number is the SR, or skill rating for the current competitive season. This usually informs you of your current place in the game from your skill. The symbol on top of the SR is called the tier which tells you which section you are in with bronze being the lowest and grandmaster being the highest. With this kind of information, you would be able to know how well you play or how much you need to improve upon playing Overwatch. All in all, through special little additions like these, Blizzard Entertainment is able to make gameplay easier and much more enjoyable.
