Proof that Code A is harder than Code S! Really though it's because he got zergs in Code A while he completely avoided them in his Code S runs (not surprising since zergs did terribly in those 2 seasons). Though honestly if you did some sort of giant teamleague event with Code A vs Code S like bo65 or something I wouldn't be surprised to see Code A win at all. Code S would be favored but it would be really close that's one of the major weaknesses of SC2 there really isn't that much of a difference difference between Code S players and every other pro.
