I dont like cs at all but like why do people care if there is a no name team in finals
I think people like to root for underdogs, watching teams have a miracle run is always fascinating.
The only issue is if becomes too much of a regular occurrence.
Having teams that can make the latter stages of tournaments regularly is good for creating rivalries and storylines.
I like to use the David versus Goliath analogy for these cases, an underdog vs an established powerhouse.
People would like to watch a "David vs Goliath", which in this case would be Gamer legion vs Vitality.
They would also like to watch two Goliaths facing off, but to have a final with two "Davids" is not as interesting.
