too many wrong excuses, Im korean and there is only one reason that why korean teams dominate in e-sports
:korean teams playstyles are very quick in general they made decision and execution quicker than any other region because of their culture and ethnicity thats all
when I watch other regions game I'm dying cause of the speed of the match they should improve that matter if they want to beat korean teams
and I will explain that why those excuses are wrong
the ping differences : KR player play the game in 5~10 ping and NA and EU player play in 60~70 ping and when I play in Japan server it is almost 70~80( I use vpn to access JP server) ping and guess what? I cant feel any difference, just ask someone who play in both KR region and NA or EU region
Korean teams have more good and experience coaches : wrong because NA and EU teams also have equally good experience coaches, kkoma who is now skt1 coach was actually known player of warcraft 3 game mode chaos which is also MOBA like dota and he was not like top player in that game actually he was more like comedian gamer so I was very surprised when I heard he is now skt1 coach, the importance of korea e-sports coaches are not from their former games or their career its their ability to observe in meta and player and the relationship between many people who are related in the scene for sharing information
korea server is more competitive : korea server or NA server or EU server they all have competitive master tier and challengers tier and it is also same that they all have trolls in lower rank tier
I also watch overwatch competitive scene and korean dominance is coming in there too which is for the same reasons : faster adapt in new meta, initiating the order faster etc...
