is liquid out of vct
This page is pretty useful for this question: https://liquipedia.net/valorant/VALORANT_Champions_Tour/2021/Circuit_Points/EMEA
The only possible scenario of Liquid going to Champs without LCQ - Acend place 16th at Berlin, while Blaze / G2 / Giants don't get into top-4, and also Gambit must win Berlin so Gambit / Fnatic / Liquid go all together to LA (Gambit by winning Berlin, Fnatic and Liquid by circuit)
In other words, it's impossible
Fnatic and Gambit are already ahead of Liquid in circuit points. Under normal circumstances, the top two circuit point teams qualify for champions directly. That is no longer possible for liquid as it stands. So Gambit would need to win Berlin to get the direct spot to champions(Fnatic is out of contention for Berlin already) and then Liquid along with Fnatic can qualify to champions directly through points. Like the above comment said, Acend need to completely bomb out in 16th place and Blaze/Giants/G2 to not get top 4 in Berlin to prevent them from surpassing the 300 points Liquid currently has.
