S Tier Teams: Optic and PRX (The only top teams, Optic because of how resilient and versatile they are and PRX because of their talent, speed and strats. The kings of adaptation and fluidity are what Optic look like and PRX are just the unbeaten speed demons. Also, either may lose to A-tier teams but that still doesn't change their superiority for me, they have proven to be the top 2 already for me, just from the eye test)
A Tier Teams: FNC, DRX and FPX (FNC is clearly the most intelligent team here, DRX is the most coordinated and had a close-ish series against Optic as well along with a clean Group stage, and FPX is just a wildcard for me, but potentially the most dangerous team in this tier capable of even winning the whole event. Suygetsu is a demon as well.)
B Tier Teams: Guild, Leviatan and Loud (Guild proved they are world-class after shutting out Optic and lost out on a close game to FPX, they also have Sayf, who I think is a top 5 fraggers at VCT. Leviatan is just so resilient, not the most strategically sound team but god they have god-tier talent, maybe expect more from them at Champions with more prep. Loud are just the most finished or complete team out of LATAM/BR, and Aspas is a monster as well, but even tactically they are super sound and complete, a real top team.)
C Tier Teams: Kru and XSET (Kru is just a really mechanically and tactically sound team with a top 5 star in Keznit, unlucky how they lost out and were in a group of death but could've easily upset teams and taken wins over other teams in this tier or even teams in the B and A tier, so Kru is probably a B tier team but I'm placing them here because of recency bias. XSET looked decent but got outclassed by Optic and then lost out of Leviatan because of multiple mistakes and their strat book is simply not good enough to compete at the highest level nor do they have the talent to cover for it barring Cryo and Zekken who looked good but still made mistakes.)
D Tier Teams: Xerxia and Northeption (Not the worst two teams but placing D because of performances and how everyone else seemed to have levelled up and they have simply not caught up. I will say both these teams need a little more experience and individuality, to escape their respective big brothers in their regions.)
