That's not what I said, if that's what you thought I meant. Think of it this way:
Regarldess of whether those people are perfect, you can't say the Kenshi matchup chart would have evolved this way without Pig's study and skill at plowing the depths of every single matchup to find every little advantage and disadvantage for top-level play. Likewise with the Sub-Zero matchup and Brady, Kabal/REO etc. Detroit/Wound/Shang. PL/Lao, etc. etc.
There are always a lot of people that contribute to the MU knowledge.. But it usually takes one or 2 people of a certain level to show people the true potential of certain situations and tools.
Imagine what would happen if half of the absolute top players were forced to study and main a less-explored character in tournaments for the next 5 months; you don't think the MU chart would change at all?
