If Liquid goes berlin they are by default going to VCT Champions :
Here it is :
Least Liquid circuit points if they go berlin = 425
Max possible Acend circuit points = 475
Max possible Gambit circuit points = 520
Max possible Guild circuit points = 450
Rest all teams even if they become runner up at berlin are < 425(liquid least points)
If liquid qualifies for berlin -
1) They remove one of the teams from Acend/ Gambit from the circuit points race.
2) Even if Guild comes 2nd(450) and Gambit comes 3rd(470) at berlin , liquid isn't finishing berlin at 13-16th position so actually there least circuit points = 475.
3)Only 1 team at max can surpass liquid in total circuit points.
PS: This is all considering Liquid defeats forZe and Ace/Gambit. Hoping so
