Sentinels : only brought eyes too how NA can be good at a game at its beginning but falls too EU later anyway
gambit : brought how having players that can play many agents too a high level is a very good
Acend : were flukers who showed that Jett and Kayo are way too overpowered for that time
Optic : showed that Neon at the beginning and Chamber with 2 TP and 2 Traps is OP
FPX : brought the legit best 2nd round buy
Loud : showed that having 4 aimers + an igl is very good for a team to win
Fnatic : new buy + importance of having a duelist be good at raze and jett + having versatile players
