The weakest link is not Kuku himself, but it's the hero pick, I don't know who decide the hero pick, but most of the time Kuku use a low-impact hero, like Venomancer and Viper, though both are great hero to win the lane, but then it's expect both the carries to snowballing, winning the lane, winning the mid game, and end the game fast, and it put so much burden for both Ana and Topson. They might be a very good player but to dominate all games everytime is kind a hard.
Aside from the drafts, they are not in sync all the time. There are times that Ana or Topson are left too deep in the enemy and their teammates are not in position to response or help them. They still have the chance to enter TI through the last chance qualifier since they ended 3rd place. They have a few days to polish their weaknesses and their plays. Hopefully, they come stronger in Last Chance.
Congratulations to Talon for qualifying for TI. It was a hard battle fought against Polaris. The wins are back and forth between Polaris and Talon but in the end, Talon got the win in game 5. Polaris was so close to making it to TI and having an underdog fairytale, but Talon is just too much in game 5.
