Its because Valorant is not EMEA's primary FPS game, its CS. Americas is all about Valorant and they create drama not just in tier 1 but even in tier 2 to sell storylines. All of that is fake btw. Almost all Pacific teams have great backing from people of their respectative countries because of nationalism plus you can always count on Japan to provide a consistent viewership.
That's exactly what other regions should be worried about, EMEA is the most successful region with 5 international trophies all won by different teams and their own people don't care about the game as much as other regions. Players like Niko, Ax1le,Yekindar etc will farm this game after getting some decent playtime.
