I'm watching OG vs NiP 2nd game right now. Pugna is still too strong even after the 7.26a nerf. It looks like NiP will win this game as well.
Edit: Sumail's void demolish them late game

Sumail Carry pos is OP but it will vary into its support.If we do try to look on game 3 which Sumail picked MK and Oracle is on back up then no doubt that he can farm that much with sustaining heal plus
life steal on 3rd and opponents was axe is just easy to handle.New OG roster is OP but there are other team which are also good. This game is 2-1 not bad for Nip.
Lets see on which team would able to go forward.
Sumail carry? I think he will take the midlaner position as in the previous team, I think OG is trying to resuffle all their roster, trying the best game from each player, it is not impossible that the sumail position as a carry will be replaced if it is not effective for him in the long run.
