Good points.
Steel is definitely a top igl and considering that is what NA extremely lacks is a big loss to the team. Them dropping steel before the LCQ is why I believe they didn’t qualify for champions.
Regarding nitro, those who say he wasn’t a big loss to the Valorant scene are just dumb. As you said he’s a top 3 smokes player in NA easily with a lot of experience and if needed can also be an igl. He is a huge loss for NA VAL.
Regarding the other two, I have no comment on babyj, I think faze is just TSM 2.0. Ec1s moving to NA will most likely help his fragging abilities regarding to skill level on players. But I think he may struggle to begin with because of the different play styles.
