Is this kind of crowd normal in CS?

I'm relatively new to CS so I'm really not judging.
But I found screaming for antieco rounds and almost every flank sorta weird to me.

I'm just curious if this is common in CS tournaments.

wait until sentinels plays in americas, its a lot worse

Unfortunately it's pretty common yeah, especially during NAVI's games

They are g2 biased crowd. And lot louder and hype compared to val crowd. val fans generally don't like such crowds. But this type of crowd is what makes Cs lans so fun too. Again can be annoying if the crowd isn't biased for your team.
