Largest Overwatch upset?

Maybe Selfless losing to YIKES!
Or Runaway beating Lunatic-Hai in APEX 2
(im trying to create threads to keep this site interesting)

Cloud 9 losing to Method @ OW Open

Fnatic beating NiP at Dreamhack

I feel like Envyus winning Apex with Mickie was a crazy upset; i don't think anyone expected a team who had just lost a star player to dominate the Koreans.

GC Busan 6-0ing Lunatic Hai this past APEX

i feel like envy losing to misfits in the OW open was quite big

Rogue ending the Envyus streak at the Atlantic Showdown over a year ago

envy winning with rogue during apex season 1
everyone was sure it was rogues tournament, by far best team in the world so sure of vistory they picked 2nd best team envy for opponent aaaand dva changes came and rogue lost

edit forgot about this season gc busans upsets by far

Kungarna beating c9 to qualify for contenders

EnVision beating Immortals at the beginning of Contenders S1 seemed like a huge upset before we saw Immortals' performance for the rest of the season.

Liquid beating Selfless in the semis of the Overwatch PIT NA was pretty big. Also eUnited losing to Movistar Riders in the EU Final.
