Ok wtf FaZe

How the hell is FaZe Clan 3rd in the rankings right now? What about C9, Envy, or any other team (besides Sentinels and V1) that qualified for Challengers Finals?

they are not, they just don't update the rankings

The rankings are the result of the Elo system , which takes consistent losses or wins to change rankings. FaZe won for a long time, and only lost a few times. C9 and NV haven't won a ton in a row consistently, leading to their rankings being lower than they should be. Going far in tournaments often boosts your rankings, and its hard to lose rankings since you don't lose a lot in tourneys since you get disqualified and don't play after losing 1/2 matches.

FaZe's ranking hasn't changed much because they haven't played much, which is because they lost early, maybe?
