Actually, the only not "star" player on Faze right now is karrigan...and even that is not entirely true, cause he has more experience than 95% of the other IGLs and he can still somewhat frag, do that makes him star IGL in my eyes. Twistzz is a star, no doubt. Ropz has been a star for all his 6 years of playing on MOUZ and Faze. Rain is arguably top 3 entry fragger of all time, and oftenly picked in dream teams by other players and coaches. Broky carried Fsze hard in the most difficult moments and has been a top 10 star player for 3 years now.
So with that said, you can have a team with like 4 star players, if they mesh well together and if the fifth is experienced and makes some sacrifices for the team. Pain are kind of a team like that, they just need more teamwork and individusl polishing. Fallen + 4 more promising stars would be magical as well, imo they need to kick boltz and especially VINI. Furia...man, I actually think art and his aggressive style are the main problem there, although having and underperforming awper like saffee is also not helping. Imo they should rebuild around yuurih and KSCERATO. 00nation needs sports psychologist badly. MIBR needs a whole new team, and the other Beazillisns are up to the level if CS played.
