Is Overwatch Good With a Controller? - First Time Playing OW2 With a Controller 

Seeing as how I I switch from playing on PC to playing on console last year necessitating dedicating time to learning how to use a controller, I can safely say there are somethings I can do better with a controller than with a mouse and keyboard and vice versa, and lot of it comes down to character movements. Such as I would never bother playing as Wrecking Ball on PC because of his cool downs, and how awkward it feels to move a sphere withe the WASD keys while trying to quick gauge where a good grapple point is, but with the analog sticks it feels a lot lot better. Another example is navigating as Dva using her thrusters, being able to bank left or right to get a little 'boop' or several in a row if timed right can push them back.

Overwatch doesn’t have aim assist on pc only on console.

Ok, now imagine playing on a switch lite with no pro controller, that is my current situation its as bad as you think
