I think in the last years it was super close... and Americas, EMEA and Pacific all had crazy good and bad times between 2021 and 2025 - but every region had teams that could beat any team from all the other regions (except CN). But this year I think it's the first year where it seems to be VERY dominating by Americas when you look at teams. Pacific has PRX, EMEA has M8 and BBL - but no consistent performance internationally shown yet, Fnatic will be back for 2027 for sure and Vitality might be crazy for next season, too - but this season not so much... and Americas has NRG, G2 - 2 absolute beasts, then LEV, FURIA (similar to M8 / BBL) and then rebuilding Sentinels and KRÜ... so many insane teams.
So yeah, def. the best region on the paper. By far. But is that good for esports? No. Look at CS. Still insanely popular in NA, CN etc. and yet 95% of the success is made by EU teams. Not very cool. It was always so nice that Valorant had great athletes and orgs in every region... so many great events were carried by that fact.
I don't want an dominating region in Valorant. And when you look at Tier 2 in Americas, EMEA and Pacific I also doubt that there will be a fully dominating region for longer than a year. So many talents everywhere.
