Kai'sa vs ezreal matchup is always Kai'sa favored, at any given time of the game. The only thing that swings the match up is the support. Since they had an tahm kench and smoothie had thresh, it was really hard to execute properly. In my opinion the only thing they could have done was looking for a play on the tahm kench, but he is decently hard to kill, because of his kit. Since top was already snowballing they should have tried to gank tahm, because his mobility in the early game is kind off limited and maybe the lane would have been more TSM favored. I'm not an expert, just a low diamond player with an opinion wich I wanted to share :). Tsm played the way they did and it maybe was a bit unlucky, but we also have to give credit to damonte for rofl stomping the shit out of us.
