From my perspective as a EU player who enjoyed most of the games I played on this website, this pug: http://sizzlingstats.com/stats/534925, was lost before the game had even begun because a few people who I don't remember the names of, spent good 10 minutes complaining and arguing (to their fellow americans, mind you!) about bad picks and continued doing so after the game had already started.
And, yes, scrambled is correct: there aren't any examples where EU players did worse than their NA counterparts, and in the pug above pretty much everyone played terribly, not just Europeans.
