Imo TL, Fnatic, Sentinels, C9 and PRX
Depends on meta a lot. In my head I would say that NaVi are the strongest. They kept 4/5 players and coach and as long as cNed can perform to decent level I think they have what it takes. Especially if Jett is meta for Sao Paolo. We will just have to see how much of an impact Ardiis had as personality within the team. Seemed like Ardiis was the guy going against ANGE1's ideas. cNed seems to be the opposite of Ardiis in that regards. I also think their map pool was horrible during Champions and big part of why they lost. Its easy to fix though.
Its just speculation. Watching their interviews etc Ardiis is clearly the loudest one with ANGE1 and seems to have strong opinions. Like when he talked about ANGE1 wanting to run Yoru and how he told him not to (in joking way). Nothing may change, but cNed seems to be pretty quiet quiet guy and he likely isn't going to say "no" to ANGE1's crazy ideas.
