Imo they had a better chance at winning in a BO3 than a BO5. Mini said they've been preparing Pearl so it's possible they ban Fracture in a very possible rematch in the final
They also might just ban haven or ascent as well and let pearl in eg has literally no footage to be able to anti strat them while fnatic has lots of info and if they ban ascent and fracture that’s 2 of their best 3 maps in my opinion banned the other top 3 map being split which is a coin toss between these 2 teams
