Looks like some teams are just used to study so hard to win against teams on their regions but when they're playing against "unknown" teams they just shock because they're not adaptability.. too much used to play against same teams so they win just studying but overall they sucks.
they study to win against specific teams but that doesn't make them good at all
Just because you can win against a TOP 1 team by studying them will not make you a better team overall.
