K so pretty much any dumbass can be in masters then? you don't need to know anything to be in masters? That makes no sense.... Yes even though NA sucks in ladder, that doesn't mean that people don't know anything in teh game. Although NA are not better then Koreans in SCII that doesn't mean they don't know anything about the game. if anything, you seem to lack any coherent sense of logical thinking. If I was silver or if people are in silver you can say that suck at the game but even then they can know the game. They just don't have practice to execute what they need to do. Like they'll forget to build supply and be supply blocked for 30 seconds. Or they'll have idle scvs, but they know all this is bad, but they just can't execute.
"playing masters still doesnt tell anything about knowing the game"
this statement contradicts itself based on the assumption that people in masters are top 2% in a region. It's like you get an A or A- instead of an A+ on a math exam and you claim they don't know anything about the math exam. Too young and naive you are. Much to learn you still have.
