I agree with all except the last. Meteos needs to go back to his comfort picks (minus Elise; Rito wtf). He keeps trying out this Rek'sai, but he doesn't play her very well at all. Meteos has always been a workhorse type of jungler and he even showed that in this game. He doesn't pressure with Rek'sai and that's something you really need to do with her. Rek'sai isn't as strong as people really think she is because there's nothing she's really bringing in competitive that others don't (aside from her amazing pressure). J4, Gnar, and Corki alone is a really strong team fighting comp and if they don't wanna teamfight, you have J4 to force those fights.
Meteos is really good on J4 and Lee Sin. Both of which can really dominate games.
Balls keeps taking this Gnar that he himself has said he doesn't perform well on. Ban the Gnar, not the Lissandra. You're good on Liss and if Zion takes her, you get your ace card Rumble.
Hai imo did pretty decently in this game, but he has the same problem with the other two above. Stick with your comfort picks. Hai is a god on Zed and for the 2nd time he didn't take it when he should of. Zed is also ridiculously strong atm, he can bully you out of lane and can also farm under tower if he's getting bullied.
They also let CLG get an amazing comp. Morg/Cait is a ridiculously strong lane. Morg/Rumble teamfighting also really strong.
I don't think C9's head is in the game even after that Liquid game. ( I'll leave this great interview here) They're coming back slowly though.
