Yeah, same as Golden. I don't know the Asian teams well enough to make guesses.
CLG I'll root for, but man their boot camps have been bad. Zion sucks at the new 'meta' top laners and everyone else just seems wishy-washy. I hope their scrims have been better than their solo-que results would suggest. Or else they're just trying to lull everyone into a false sense of security by not putting forth any real effort there.
If they put as much research and preparation into all of their matches as they did for the NA championships then they at least have a shot. Against KOO Tigers though I think they'll fail to close out games decisively enough and get to mid/late game when KOO will destroy them in team fights.
Indifferently devoted to a truly outrageous yet mundane heroic epic.
