I can't think of one major game where when Asian teams are participating, NA teams are considered stronger.
Of the top of my head, right now. In LoL and Starcraft 1 and 2, North America is pathetic compared to how the Asian players and teams play. It's funny though, I have to say North America was on the top of EVERYTHING, economically, technologically etc. Now they are just starting to lag behind the rest of the world...even in video games.
Also awesome meta in the games so far, really enjoying the change. Those Asian teams are incredible at adapting O.o
