...That is the stupidest reason I have ever heard.

People USUALLY have 1 good race, I've seen 2 gosus that are good at all races (and they are REAL good at terran)

1, was one of the FIRST gosus (probably 2nd 3rd or 4th) and also won the first WGTour, LarryTheWeird.

2, is another friend of mine, breeze, used to play 16 hours a day...

Not even Slayer (the best micro management in the world) is best with all races.
