TSM loses vs one of the 2 favorites on the WC title.
Dyrus has to lane against a player that let Voboy look like a 1200 Elo player.
And why did Dyrus lose the games?
Sure he did mistakes, some that were not needed. But the team was able to recover from that.
In the first game it was the 5 man baron call and the tower dive after that. TSM was getting back into the game against a poke comp, but they wanted too much and gave up a lot of towers and extra money cause of that.
Dyrus even came back from his bad early game and did a lot of great things in the tam fights in game one.
The second game was actually a mistake of TOO, Xpecial and Chaox.
Having around 3k advantage but still buying less wards than the enemy, buying no oracle and then, when Karthus has no ult and Chaox has no ignite, they start the initiation onto Taric (withut any real vision there)
That one bad fight was a 2 kill, 1 drake, 1 tower, around 20 CS change => around 3k worth of gold.
Sure, Dyrus should have pressured top more, but that wouldn't have changed the team fights.
And TOO shouldn't take all the kills. Securing a kill is good, taking all the kills is not really needed on Maokai.
It was not up to Dyrus to lose this but to the team.
And picks are not a solo thing, but decided by the team. Sure, the top laner says what he wants, but the team can say "NO".
People have such a tunnel vision.
