Even Monster Energy said it.
The second map (Cobble, an nV favorite) ended with a 3 way tie for top frag between Kioshima, KennyS and NBK, with 23 apiece. With the resounding victory, nV stomped Fnatic on Cache. 16-2. 16-2 is a scoreline expected in group stages against an NA team, not a quarterfinal against the team widely believed to be the best in the world. This was regicide.
