Not ranked, like VCT and shit.
Why not, tons of high level matches and great players/personalities also it is way more chaotic and content than EU, but the real question would be why NA doesnt watch anything other than their region? I get that valorant community is too casual atm and most are nonamers but I guess its getting better, looks like a lot of NA pros are watching EU matches nowadays and also hopefully players who got popular recently from international tounrmanets performance attract more international viewers
