I mean, Korean Valorant scene is sleeper but their production teams are world class. I remember for PUBG (Obviously since it's a Korean game), they have Korean staff run every event for the most part and the World Cup they hosted in Bangkok also used Korean production and it went pretty smooth.
That being said, why use a non-localised TO from Indonesia rather than using the existing TO's we have in Thailand or import some good production teams from Korea (I guess the answer lies in the question since Indonesian staff is much cheaper than Koreans). This is the pinnacle of T2 in APAC, it's not T1, but it should be much better than this.
From scuffed audio on the English stream for many concurrent rounds, shitty replays that are laggy and not coherent, no audio from player cams, the viewer experience is just not very good. The venue is hella small so there's no hype whatsoever (also, Thai fans, we gotta work on our tournament etiquette)
