There was no competition because Astralis were just miles ahead of everyone. All of the other teams competed with each other, while Astralis just dominated and won nearly everything. You could say the same about literally any other team who has dominated for a period of time in CS history. Fnatic? oh nah not competitive era, SK/Luminosity? nah man not that good. NaVi 2021? you get the point. Liquid were the only ones who stood up to them and they got spanked pretty much every time by Astralis.
