That was heartbreaking for C9, they should be proud though. A team just over two weeks ago that wasn't considered a top 10 team has for two weekends in a row been very competitive with the #1 and #3 team in the world.
They've proven it wasn't just a fluke, they're a legitimately *much* better team. I had Na'Vi to win it and fnatic before that just down to experience. There are experienced players on C9, but as a team they need some more experience at this absolute top level of play before they can more convincingly take maps off these teams. The ability to reset when things aren't going your way and to close out games are key characteristics which are separating C9 from most of the top 5 level teams.
I think they can definitely get there though if they manage to keep a hold of this form for long enough.
