Something that I just noticed is that all the teams in the top 3 from Copenhagen didn't have roster changes for quite a bit of time
Optic/Envy - Yay in August 2021 (chet in October if that counts)
Prx - The entire roster was together since February 2021
Fpx - Ardiis in December 2021 (but the closest one was Doombros in May 2021)
Maybe the formula to doing well in Masters is sticking to one roster and not making changes? looking at you Fnatic
