For me at this moment, its C9B and XSET, but if TSM gets Corey (not sure if it's confirmed) then maybe. Really excited for the 2022 NA Valorant.
In terms of actual ceiling, I would, sadly, still say Sentinels. Sentinels have shown that fragging isn't an issue, as they have had more FKs in all of their series than their competition. On the other hand, too much ego peeking which lets teams crawl back, (Tenz on Split...).
I think NA will be competitive because NA will not have IMPLODED rosters competing, but I have doubts about TSM being any higher than Top 4 because of how Wardell plays Jett.
