Huhi is fine
He makes it hard to most teams to play against CLG because they can't ban him out. They just have to let him play whatever he normally wants. The issue this season is that they lost a big time jungle xSmithie and the meta isn't good for mid lane. There are 4 actually viable AP carry champions, 2 AD Champions, and 1 tank champion. So even if he picks a champion that no one wants to play, it's not very effective. Look at the game where he played Velkoz. He ults 5 people, they all lived... yet a Orianna with same items would have destroyed
Anyways, CLG needs to get a better jungle or Omergod needs to improve. A lot of their loses came down to their jungle not doing what he should have been doing. Walking into a brush into 5 people. Trying to attack a tank while the enemy is attacking an elder..etc. It's not all his fault; he has to delivery at the end of a season against top 6 teams; that's really not easy.
So CLG losing to C9/IMT/TSM doesn't make them bad. It's consistent with NA history. TSM and C9 tend to be the best followed by CLG...
