The result of the Astralis vs HEROIC matchup in the grand final wasn't surprising at all in my opinion.
HEROIC were already the absolute favourite above all else. Their odd was like 1.30 and 2.95 was the odd given to Astralis. I assume many people tried their luck with Astralis after seeing their incredible rise in BLAST Premier Fall Showdown. They were unexpectedly solid until reaching this stage. However I was much closer to HEROIC here as their performance wasn't alike to even Vitality's. They were eager to be the winner of the tournament as much as Astralis. And they showed it by a solid 2-0 victory (22-20 on Ancient, 16-10 on Nuke).
TeSeS was very impressive especially on Ancient with 40 kills.
This was the most impressive round of him which he got 4 kills (2 with Deagle and 2 with Galil):
