Vision Strikers are pretty good, but i think they can be better if they play in another region. APAC in general can't even fight them. I hope Riot allow them to play in NA/EU in the future.
they would benefit from it but unfortunately not realistic. also it's better for the asian scene in general for them to stay, other teams learn a lot from playing against them and studying them
I think the same applies for KRU, i would love to see them play in the NA circuit because it feels like they just bully the other teams in latam then have unfortunate performances at LAN
