The ONLY EU team I see as an international threat
Is UOL.
Fnatic and SK might be good regionally but UOL is gonna be the only good one on the international stage. They pull cheese like no other. When's the last time an European team not named UOL did well in an international event since LAST SEASON WORLDS?
Can't say NA has only 1 good international team tbh. If we're talking "pure" NA teams I'd say C9 is still retardedly good as well as TL (if they ever get out of 4th) and CLG (didn't make the cut though). And outside of those, TSM still looks to be dominating on an international stage as long as they don't get cheesed the living fuck out of.
In conclusion, NA > EU
