I wouldn't call TH top 5 EMEA yet. NaVi, TL, Fnatic, KOI, GIA, even VIT are all in contention for top 5 in my head, but ofc their potential is high if the players are having good form.
Although I would not buy too far into these games, the first international lan within franchising isn't until February, so the next couple of months will see big changes in levels of play of the newly built rosters.
