I am thinking it was more a case of PSG believing they have the game when Tiny-Lycan combo passed trough. Colapse is player of the tournament for me with his performances on Mars and Magnus.
Did not think Team Spirit will win this one after LDG destroyed them on map 4. Big congrats to young Russian team.
LGD kept being confident that they could handle TS Magnus, look what happened. Granted it was also a bait by TS with them leaving Tiny open from what I can see though. I honestly thought LGD was doing a huge comeback they performed astoundingly well in games 3 and 4, and even in Game 5 they got the Tiny-Lycan combo BUT again, they left out Magnus without any hard counter. Game 3 had Rubick to counter him, and we all saw how Collapse's entry was always denied.
I think LGD thought they broke TS's magnus after winning game 3 and 4 but in game 5、 a different story was unveiled and their lack of respect to these young team paid them the prize. Team Spirit is a dark horse in TI10 indeed.
Yes, they believed they'd shatter the TS Magnus, but collapse is completely different, so they're still picking it, and the team trusted him with that hero. That's one of LGD's mistakes; they should've respect ban on Magnus, and I think it's a bad decision to display their awesome draft (lycan tiny) in the battle between team secret; perhaps team spirit already knows about this draft and is preparing for it. I checked Team Spirit's recent matches, notably in the Easter qualifiers, and they've managed to stay in the upper bracket, indicating that they're more than just a normal dota2 team.
