Sigma can dominate dva if done right. Absorb her rockets or shield and rock her on her dives.
Sombra is an absolute menace to dva if she wants to be. I’m gotten shut down by some good sombra’s playing Dva.
Those are two off the top of my head.
So use beam heroes? Problem solved. Dva does nothing or protects anyone and she feeds like crazy while your team laughs and steamrolls.
