See this isn't fair. When the outcomes of the tournament are either 'lul NA got crushed' or 'EU never shows up at these tournaments, it doesn't count' why should anyone care about your opinion? I was ready for NA to get stomped and I would've just said 'welp, that's life as an NA fan' then been pleasantly surprised. Fnatic got their dream team comp that they've been dominating the EU with and still got crushed. Throwing your best strategies at teams and losing isn't 'not caring'. It's finding out maybe your strategies aren't bad.
I don't think this tournament means a lot for worlds because to roughly quote doublelift, EU is not a bad region. They'll take this tournament and learn from it and probably incorporate stuff they lost to and get better. But this tournament was humiliating because people were expecting FNC to go 5-1, 6-0 and they only took games off P1. TSM out team fought UoL. G2... well they've been having troubles in the EULCS.
In this tournament NA was better. One side didn't care more or less. It doesn't mean NA is always better as we know from plenty of past experience.
