The only maps that NIP are better than NaVi are Inferno and Vertigo indeed. Ancient is neutral for the sides so I think this map is very likely to be picked by one of the sides. But considering the probable bans and picks, NIP are going to be very disadvantageous anyway.
Besides, NIP have a very low chance to create their second chance by this match even if they win. Because NIP's total round difference in the group is -37 now. The closest team that they need to get past are NaVi which have a 12 round difference in total. NIP must defeat NaVi by a huge difference which is the only way for them to perform a miracle today. I think there is no chance for this. I don't think NaVi would leave their job to chance here. So NaVi win can be added to the betslips @1.23.
Yup, NIP's map pool is poor. And dang, it was Inferno, Mirage, and Overpass instead of Ancient. Easily to guess the win for both teams in their map pick. NIP will win the Inferno as their pick while Navi will win the Mirage as well. 2-1 in Overpass to decide who's going to have a chance in group stage A. Although NIP has -37 and 1-3 win/lose, if both Spirit and Endpoint lose at a huge margin, Navi loses to NIP too, there might be something ugly going on in group stage A.
@Distraction:
Luckily, all three matches of Vitality vs Spirit, Fnatic vs Endpoint, and Navi vs NIP both happened at the same time. Fixing will be hard. As you said, Vitality can just let Spirit win at a huge margin to kick both Navi #1 and NIP #6 out, less dangerous teams in the playoff rounds. Or NIP could drag Navi down with them that even with a win, Navi's round difference isn't enough against Spirit.
