In Overwatch, you can view a number of statistics on various heroes you've played throughout the game. One of the notable ones to look at is "Games Won".
One might think that if you play a game and use a hero, you've played one game as that hero, and if you win that game, it should count towards your "games won" for that hero.
But Overwatch is also a game where you can change heroes halfway through a game - starting as one, then changing if things go poorly or if the situation calls for it.
So if I start a game as one hero, then finish it as another, and win, how does the game count how many "Games Won" to add to which heroes?
To clarify: On the "Overview" page, if I select "games won" in the "Hero comparison", if I use several heroes during a single game, which hero(s) "games won" would increase?
