I feel like CLG is doing really good lately, especially on LAN. They sort of remind of old NaVi in that they are offline beasts but they're not so good online. I just hope Fugly matures a little faster. He's often taking premature peaks, peaks too often, and commits to fights that will screw his team over if he loses. However, with JDM's form and just a solid core lineup they just keep going further and further.
IMO, they're the best team in NA atm besides the Brazilians. Liquid have fallen off since Koosta doesn't know what's he's doing and C9 are still transitioning after lineup changes.
