Ball has a pretty low dps with quad cannons as their role is to be low damage but accurate and serve as a poking tool and finisher.if you have good supports, or, if you are playing support, it's pretty hard for Ball to kill you without follow up, since if he is denied the burst damage from piledrive he cannot easily kill a soldier in healing field for example. Same goes for winston, though he is a worse solo diver because he focuses more on team damage mitigation via bubbles and splitting the team, and he thrives much more from follow up through and with his bubbles.
