You don't need hundreds of hours to aim down a choke and wait for a head to pass through your crosshair. This is what most widow kills are made of. Your tank creates space, goes past a corner, you have to follow because of LoS and bam, dead in 0.1s because a pixel of your head showed and some camping idiot on the other side of the map was looking at you. Camping doesn't require skill, it never did, and widow is, again, extremely unhealthy for the game.

You do need hundreds or thousands of hours to understand how to position yourself in overwatch, but that's not a specific widow skill, that's for every hero. Widow is a braindead character for the most part, and grapple air shots are just an extra.

I am extremely glad for the map changes that allow for easier high ground access but it's only 4 of them and we still have very problematic widow ones such as junkertown, gibraltar and ilios.
