In this Overwatch clip posted by Reddit user DJgodsonfire, a Wrecking Ball player manages to outplay D.Va purely by accident. The D.Va just happened to make the wrong call at exactly the right time.
The clip starts out with Wrecking Ball just doing their thing, rolling around, and knocking into the enemy team. Then the player takes cover quickly before they build up their speed again but gets slapped with an Orb of Discord from Zenyatta.
The Wrecking Ball decides they want none of that and takes out the lone omnic handily before heading into melee with D.Va. Things start out well for the D.Va and the Wrecking Ball is forced to retreat into a nearby building to grab a health pick up. Wrecking Ball then tries to make a hasty retreat through the opposite door from where they came in and smacks right into D.Va, who looped around trying to cut Wrecking Ball off while they were still recovering. It ends up being the wrong call though because the D.Va ends up getting a face full of hamster ball and is eliminated from the match. Just goes to show you, even the best plans can't always stand up to the randomness of human behavior and the inevitability of bad timing.
