A Tracer player snags a 6K with the help of a Zarya ultimate. While Zarya is easily one of the best combination characters in the game, it takes one more player to make the magic happen. Sure, if a Zarya is fully charged, she can get a 6K on her own, but in higher elos, you want the help.
Thats where the Tracer comes in handy. It should be noted, the Reinhardt decided to throw in his ultimate too, though he took too long getting in there and swinging his hammer. All the team really needed was one Tracer bomb.
Redditor amidisse posted the clip online, and while they were happy with the results, they didn't receive Play of the Game. However, Reddit was quick to point out Zarya made the play happen. While the Tracer bomb did finish off the team, the only reason it worked was the Zarya ultimate keeping them stuck all in one place.
DPS players need to realize the importance of tanks and support characters. Your amazing plays and clips are usually only possible because of a teammate. Maybe they gave you a clutch heal, or distracted the enemy for you, or even set you up with an ultimate.
Yes, you will have opportunities to carry games by yourself, but Overwatch was made to be played together.
