This is actually not a bad dark horse suggestion. I like it.
NOVA has been getting better and better, especially now with a fully chinese roster. Swerl isn't a bad player by any means, but as pointed out by Ezeir, communications are much more important than just a talented player (Verno on NRG ahem)
KRU came really close to hitting top 3 for Americas, it's unfortunate that they played the goat and he absolutely mopped the floor with them.
Not really an EMEA watcher but M8 was really competitive, I still think there are better teams though, maybe Heretics and KC? KC only lost a very close series to VIT and Heretics may have had time to pick up on the Tejo meta ever since their kickoff run ended.
As for Pacific, I think this is the most difficult to tell. Pacific has tons of good teams that could make Top 3. All the korean teams look really strong right now, Nongshim probably being the weakest, but that's kind of expected when all the korean teams are pretty much champions (except for DRX). I do still want PRX to go the Toronto though.
