My predictions are :
NA: SEN + C9 + ABX, I think andbox have upset potential but honestly everyone in na does cause everyone is making changes so who knows
EMEA: FNC + ASCEND + BLAZE + GAMBIT, blaze and gambit seem like solid teams and all the other teams in europe are too inconsistent, maybe liquid if they step it up
BRAZIL: FURIA + VIKINGS, honestly idk much about brazil but I heard these teams are good
KOREA: NUTURN + VISION STRIKERS, best 2 teams in korea for sure
JAPAN: ABSOLUTE JUPITER + CRAZY RACCONS, best 2 teams in japan
SEA: X10 + IDK, no clue about sea region
LATAM: KRU, best team in latam
These are just guesses from a silver player so don't be mad
