I think that may have been true at one point, but of the team still residing in Europe I'm not sure whether anyone below the top four (Misfits/Rogue/NiP/REUNITED) is better than the top ten of NA. They have reaped the benefits of a solid circuit and the NA tier two seems much deeper than the EU equivalent currently. It's also hard to tell because we haven't seen the EU teams compete in two months but this lack of opportunity has only served to separate the gap between tier 1 and 2 in Europe. I'm excited to watch even French casts of the G4G XTRA Cup because we can finally see something from Europe.
It's also worrying that TOs are finding it not worth their while to run regular small (5-10k) tournaments in Europe. The viewership figures and budgets are a feedback loop that only serves to send the scene downwards, perhaps exacerbated by the decisions to run all tournaments at NA hours early in the game's life. This is a prime opportunity to get more bang for your buck as the only tournament happening in EU right now, even if you believe the viewership will be lower.
End of the day though, this is a very reversible issue. If 2017 continues like this with incredibly few opportunities for EU I'd be amazed.
