if that were the case then they should have stepped their game up during the summer split when cloud 9 was dominating. and while the teams did all look better at the end of the season (tsm and dig in particular were doing a lot better in august than in june), it still wasn't even a contest in playoffs, c9 shit on dig 2-0 and tsm 3-0. so i don't think adding yet another "op" team is gonna help na teams get better.
i know this is a little premature since we haven't even seen how na fares at worlds yet, but i think all the na teams (with the exception of c9) need to forget about everything else and make LoL their entire life if they want to perform on the level of the koreans and the chinese. multiple top level players like flame, madlife, imp, etc. have stated outright that league is all they ever think about. they focus entirely on one thing and achieve mastery of it - reminiscent of the ancient japanese craftsmen who ate, slept, and breathed their work. na just isn't there yet
