She is - no lie - hard mode. Particularly on console. But you can be devastating.

My best POTG was a single-person defence of Hanamura first point, down five on one. They'd all but team-killed us, losing only one of their own team in the process - I'd only survived because they got me separately, first.

From the point I popped D.va out of her mech, and she fled. (Fool! :D ) Then I two-shot their Junkrat, and one-shot their Moira, and their McCree. Genji tried to flank to his right (our left), and I hit him hard going into the little building by the choke, but not hard enough, and I was screaming into comms, because a good Genji will fuck me up... but then I nailed him coming out the upper door and said, "Oh, nevermind. Genji solved."

When it replayed as POTG (minus the Genji kill, which took too long to be included) our Reinhardt, who had given me shit for picking Widow, literally just breathed out the word, "....fuck" as I was taking out the cowboy, and I just laughed, and laughed, and laughed.

"And this," I said, "is why I play Widowmaker." （⌒▽⌒）
