These lag issues, at least in Europe, are getting ridiculous now. It has been almost two months from release and it's still a huge issue. Almost every lobby is a lagfest when it's prime time, and now that it's Christmas and there is huge traffic, even some less common hours are becoming lagfests.
Basically: when lots of people are playing, this game starts to lag hard. There seems to be no method at all to avoid it. It's absolutely unplayable during lag hours too, can't even wallrun because you suddenly rewind backwards into the air where you fall.
