Yes, I'm not determining who is a star based on ratings. REZ shares with Brollan, he's not a star. Stavn has far better stats than any teammate, and he's even above the 1.2, but he's not a star. Ax1le has stats nearly as good as Sh1ro, but he is not the star player of the team.
You see who is the star on the team, and then look at the ratings, and they just happen to all be above 1.2.
Spinx doesn't have the role of a star, so his stats are definitely good enough, he is supposed to share responsibilities in the team with Hades and Dycha, it's them who are underperforming.
