Who have blank ever upset?

Difference is OPC is a more drawn out tournament with more matches. And the point was that the teams in OPC are weak apart from Aredont and fw, big fish in a small pond.

Let's not kid ourselves the competition in OPC was pretty garbage.
You have Aredont who are clearly 1-1.5 tiers higher than flash wolves, Flash wolves are then clearly a tier higher than ahq/blank/hka, those teams clearly higher than mega/machi and let's not talk about libalent.
You need to compare the teams to the competition. Every team was garbage compared to aredont, every team but aredont was garbage compared to flashwolves.
So when you have a comp with only 8 teams and there are clearly defined skill gaps and tiers it's a pretty horrible tournament. Say if you had a league 15 teams that would be understandable but not here.
