Seriously. What is the unique feature DPS have that nobody else can offer?
Good burst damage: Rein, Dva, Roadhog, and charged Zarya.
Good sustained damage: Rein, Orisa, charged Zarya, and arguably Winston.
Good mobility: Winston, Hammond, and Dva.
Good offensive ultimates: Rein, Dva, Winston, Zarya. And they’re almost all better than DPS offensive ults.
Good range: Orisa.
