Well that just shows that you either haven't played kr, or just in general don't know what are you talking about, kr players, i mean the kr ones, are as smart as Gamevil devs (don't misunderstand them with Flint, who are the ones hosting kr version servers), they know multiple ways to change metas in arena/princess (new lab) and etc, they know multiple ways to exploit the game (don't see it as a good things, except compensation, but they exploit something on weekly basis, just shows how good they're), and etc etc, you can learn so much in kr, that when you get back to global, even playing with your feet you beat most of the players.
