They didnt fall off, remember RedBull last year with new FPX? They were shit, ANGE1 is a csgo old dog, csgo veterans tend to use scrims/small tournaments just to learn regardless of result so they were probably trying things and trying to learn as much as possible about what they should do in the future. I wouldnt worry about them either since they are the team with the best prep for matches so it can be hard sometimes to play these tournaments without knowing what the other team might do
