And Astralis lost to AGO and EX-SS. Does that mean those teams are better than Astralis and should be ranked one? Either you are new to cs or you are stupid and have no clue how ranking works. And Ence lost to Forze after major, does that make Forze a top 5 team? NO
Top teams get upset now and then, it happens, its about consistency. And liquid have consistently beat other top teams to become rank #2. Not to mention they are yet the only team that was able to beat Astralis this year, and how many finals have they got to by beating top teams such as Navi, Faze.
