C9 shows how horrible people can adapt to out of Meta Picks...
TIP picked Soraka 2 games in a row, again C9 didnt bother to pick any champ that can actually jump on her and delete her in teamfights, instead they again chose a frontline battle comp, which is actually where Soraka shines...
What are they hoping for? Karma and Ahri sniping her? If the enemy team picks Soraka, all you have to do is to pick an Assassin that can jump her and kill her before she can do.... oh wait, when she is in danger, she cant do anything anyway.
Just from the top of my head, I can name: Kha'zix, Diana, Zed, Yasuo and Rengar, who are all viable picks and able to delete Soraka in no time, making the game 4v5 for TIP.
But hell, guess powerhouse frontline will work C9, just dont leave the metagame comfort zone...
